módulo de carga de dados (DataLoader):
ElasticSearch, mongodb
módulo recomendação Estatística (StatisticRecommender):
Apenas mongodb usado
LFM, ALS módulo (OfflineRecommender):
Apenas mongodb usado
Após esta etapa é longo, em seguida, concluir o ALSTrainer, correndo sobre OfflineRecommender
módulo de recomendação em tempo real (streamingrecommender):
MongoDB, Redis, kafka, zookeeper
módulos de recomendação com base em conteúdo:
mongodb, kafka, canal, ElasticSearch, Redis
Note que quando toda a articulação do sistema de depuração para re-criar um tópico no kafka: log, ele não disse de vídeo
./bin/kafka-console-producer.sh-list --broker localhost: 9092 log --topic
O tópico de recommender não exclua criado anteriormente, tudo bem
mongodb em
AverageMovie estatística recomendado
ContentMovieRecs recomendado conteúdo
de cinema de dados brutos
MovieRecs está escondido modelo semântico calculados de similaridade
UserRecs é recomendado desligada
Assim, a cor, descrição é copiá-lo para o interior do item, mas não adicionado ao maven projeto
Porque esse projeto é o arquivo pom pai não sabe disso
Então, precisamos dar-lhe adicionado a ele
Primeiro começar tratador e, em seguida, iniciar kafka
Quando você começar a kafka, não é uma boa idéia para adicionar começo tranquilo -daemon, ou se há algo de errado se você não sabe
Erro ①:
AVISAR [Produtor clientId = consola-produtor] Ligação ao nó -1 (localhost
/127.0.0.1:9092) não pôde ser estabelecida. Corretor não podem estar disponíveis. (org.apache.kafka.clients.Ne
tworkClient)
O motivo: kafka começar errado, não arranca, está em kafka-server-iniciar esta etapa do problema, não tem que kafka-consola-produtor desta etapa, kafka problemas começam a ver o erro ②
Erro ②:
org.apache.kafka.common.KafkaException: Diretório Encontrado / home / Ubuntu / kafka / logs-1 / tratador, 'zookee
por' não é na forma de tema-partição ou tópico-partition.uniqueId-delete (se marcado para deletio
n).
Diretórios de log de Kafka (e crianças) deve conter apenas dados tópico Kafka.
Motivo: kafka caminho de armazenamento log / home / ubuntu eu definir / kafka / logs-1
No entanto, devem ter início antes também, registros-1, que tem uma pasta de arquivo, de modo que os registros-1 pasta excluída como
Se você se sentir inseguro ou apenas renomear registros-1 mv registra-2
Erro ③:
Erro enquanto metadados atraente com ID de correlação 1: {recomendador = LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)
O motivo: Configuração server.properties kafka na advertised.listener comentada, bem uncomment
kafka arranjo server.properties Bases

This must be set to a unique integer for each broker. broker.id=0 ############################# Socket Server Settings ############################# # The address the socket server listens on. It will get the value returned from # java.net.InetAddress.getCanonicalHostName() if not configured. # FORMAT: # listeners = listener_name://host_name:port # EXAMPLE: # listeners = PLAINTEXT://your.host.name:9092 listeners=PLAINTEXT://127.0.0.1:9092 # Hostname and port the broker will advertise to producers and consumers. If not set, # it uses the value for "listeners" if configured. Otherwise, it will use the value # returned from java.net.InetAddress.getCanonicalHostName(). advertised.listeners=PLAINTEXT://127.0.0.1:9092 # Maps listener names to security protocols, the default is for them to be the same. See the config documentation for more details #listener.security.protocol.map=PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL # The number of threads that the server uses for receiving requests from the network and sending responses to the network num.network.threads=3 # The number of threads that the server uses for processing requests, which may include disk I/O num.io.threads=8 # The send buffer (SO_SNDBUF) used by the socket server socket.send.buffer.bytes=102400 # The receive buffer (SO_RCVBUF) used by the socket server socket.receive.buffer.bytes=102400 # The maximum size of a request that the socket server will accept (protection against OOM) socket.request.max.bytes=104857600 ############################# Log Basics ############################# # A comma separated list of directories under which to store log files log.dirs=/home/ubuntu/kafka/logs-1 # The default number of log partitions per topic. More partitions allow greater # parallelism for consumption, but this will also result in more files across # the brokers. num.partitions=1 # The number of threads per data directory to be used for log recovery at startup and flushing at shutdown. # This value is recommended to be increased for installations with data dirs located in RAID array. num.recovery.threads.per.data.dir=1 ############################# Internal Topic Settings ############################# # The replication factor for the group metadata internal topics "__consumer_offsets" and "__transaction_state" # For anything other than development testing, a value greater than 1 is recommended for to ensure availability such as 3. offsets.topic.replication.factor=1 transaction.state.log.replication.factor=1 transaction.state.log.min.isr=1 ############################# Log Flush Policy ############################# # Messages are immediately written to the filesystem but by default we only fsync() to sync # the OS cache lazily. The following configurations control the flush of data to disk. # There are a few important trade-offs here: # 1. Durability: Unflushed data may be lost if you are not using replication. # 2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush. # 3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks. # The settings below allow one to configure the flush policy to flush data after a period of time or # every N messages (or both). This can be done globally and overridden on a per-topic basis. # The number of messages to accept before forcing a flush of data to disk #log.flush.interval.messages=10000 # The maximum amount of time a message can sit in a log before we force a flush #log.flush.interval.ms=1000 ############################# Log Retention Policy ############################# # The following configurations control the disposal of log segments. The policy can # be set to delete segments after a period of time, or after a given size has accumulated. # A segment will be deleted whenever *either* of these criteria are met. Deletion always happens # from the end of the log. # The minimum age of a log file to be eligible for deletion due to age log.retention.hours=168 # A size-based retention policy for logs. Segments are pruned from the log unless the remaining # segments drop below log.retention.bytes. Functions independently of log.retention.hours. #log.retention.bytes=1073741824 # The maximum size of a log segment file. When this size is reached a new log segment will be created. log.segment.bytes=1073741824 # The interval at which log segments are checked to see if they can be deleted according # to the retention policies log.retention.check.interval.ms=300000 ############################# Zookeeper ############################# # Zookeeper connection string (see zookeeper docs for details). # This is a comma separated host:port pairs, each corresponding to a zk # server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002". # You can also append an optional chroot string to the urls to specify the # root directory for all kafka znodes. zookeeper.connect=127.0.0.1:2181 # Timeout in ms for connecting to zookeeper zookeeper.connection.timeout.ms=6000 ############################# Group Coordinator Settings ############################# # The following configuration specifies the time, in milliseconds, that the GroupCoordinator will delay the initial consumer rebalance. # The rebalance will be further delayed by the value of group.initial.rebalance.delay.ms as new members join the group, up to a maximum of max.poll.interval.ms. # The default value for this is 3 seconds. # We override this to 0 here as it makes for a better out-of-the-box experience for development and testing. # However, in production environments the default value of 3 seconds is more suitable as this will help to avoid unnecessary, and potentially expensive, rebalances during application startup. group.initial.rebalance.delay.ms=0
Quando todo o sistema de depuração conjunta, agent.log não têm dados de aplicativos de dados e StreamingRecommender
O ctrl + c calha off e reinicie-o antes de um bom poucos dados têm vindo
Mas calha não consigo tempo real, alguns dados podem transmitir antes desligue após o reinício, eu não sei por que .......
