java.lang.NoClassDefFoundError: org/apache/hive/hcatalog/streaming/RecordWriter
1、 没有导入依赖
2、 有可能maven没有下载完整
3、 包冲突的问题
没有依赖包----flume中缺少某个包
1、 根据异常信息，确定缺少什么包
根据网上的搜索信息，确定缺少某一个包：
find / -name 'hive-hcatalog-core*'
根据link文件过滤、版本对比、猜测等，优先选择了一个jar包
/opt/cloudera/parcels/CDH-5.11.1-1.cdh5.11.1.p0.4/jars/hive-hcatalog-core-1.1.0-cdh5.11.1.jar
2、 如果找到的包正好是自己要的包的话，将包放在什么地方？
通过flume-ng启动时产生的日志信息
/opt/cloudera/parcels/CDH-5.11.1-1.cdh5.11.1.p0.4/lib/flume-ng/lib/*
3、 问题解决
cp /opt/cloudera/parcels/CDH-5.11.1-1.cdh5.11.1.p0.4/jars/hive-hcatalog-streaming-1.1.0-cdh5.11.1.jar /opt/cloudera/parcels/CDH-5.11.1-1.cdh5.11.1.p0.4/lib/flume-ng/lib/
可以采用链接的方式来解决：
ln -s /opt/cloudera/parcels/CDH-5.11.1-1.cdh5.11.1.p0.4/jars/hive-hcatalog-streaming-1.1.0-cdh5.11.1.jar hive-hcatalog-streaming-1.1.0-cdh5.11.1.jar
异常：java.lang.NoClassDefFoundError: org/apache/hadoop/hive/metastore/api/MetaException

异常：Cannot stream to table that has not been bucketed : {metaStoreUri='thrift://master:9083', database='default', table='t_pages', partitionVals=[] }
Hive对接的时候需要将表设置成桶表 create table t_pages( date string, user_id string, session_id string, page_id string, action_time string, search_keyword string, click_category_id string, click_product_id string, order_category_ids string, order_product_ids string, pay_category_ids string, pay_product_ids string, city_id string ) CLUSTERED BY (city_id) INTO 20 BUCKETS ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t'; |
异常：org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat cannot be cast to org.apache.hadoop.hive.ql.io.AcidOutputFormat
AcidOutputFormat的类只有OrcOutputFormat, Hive表需要stored as orc create table t_pages( date string, user_id string, session_id string, page_id string, action_time string, search_keyword string, click_category_id string, click_product_id string, order_category_ids string, order_product_ids string, pay_category_ids string, pay_product_ids string, city_id string ) CLUSTERED BY (city_id) INTO 20 BUCKETS ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t' STORED AS ORC; |
测试，在hive当中去看是否有当前数据
4、 修改sources
capacity 100 full, consider committing more frequently, increasing capacity, or increasing thread count
5、 最好将channel的存储转为文件
