案例背景：
在 flume采集多Source、多Channel和多Sink的案例实现中，test-flume-into-hbase-multi- position.conf配置文件Channel如下:
# 配置Channel信息
agent.channels.file-channel-1.type = file
agent.channels.file-channel-1.checkpointDir = /data/flume-hbase-test/checkpoint
agent.channels.file-channel-1.dataDirs = /home/hadoop/flume-hbase-test/data/
agent.channels.file-channel-2.type = file
agent.channels.file-channel-2.checkpointDir = /data/flume-hbase-test/checkpoint2
agent.channels.file-channel-2.dataDirs = /home/hadoop/flume-hbase-test/data2/
在启动flume ： hadoop@master:/data/bigdata/apache-flume-1.8.0-bin/bin$ ./flume-ng agent -n agent -f ../conf/test-flume-into-hbase-multi-position.conf -c ../conf/ -Dflume.root.logger=INFO,console 控制台一直报错。
报错内容如下：
flume Cannot lock /home/hadoop/.flume/file-channel/data. The directory is already
Cannot lock /home/hadoop/.flume/file-channel/data. The directory is already locked. [channel=file-channel-1]
大致意思是：/home/hadoop/.flume/file-channel/data目录被锁定，我想我的配置文件中dataDirs明明是 /home/hadoop/flume-hbase-test/ 在各大平台找了个遍都没找到解决办法，于是翻墙出去看到这些话：
还有一张图（忘记截图了）说的是，你不应该在同一目录下用不同的文件 eg: /data/data1 和 /data/data2 （这里就可能会发生目录被占用或锁定），你应该在不同目录去使用 eg: /data/data 和 /data2/data
于是配置文件进行了更改：
# 配置Channel信息
agent.channels.file-channel-1.type = file
agent.channels.file-channel-1.checkpointDir = /data/flume-hbase-test/checkpoint
agent.channels.file-channel-1.dataDirs = /home/hadoop/flume-hbase-test/data/
agent.channels.file-channel-2.type = file
agent.channels.file-channel-2.checkpointDir = /data/flume-hbase-test2/checkpoint
agent.channels.file-channel-2.dataDirs = /home/hadoop/flume-hbase-test2/data/
顺利解决问题，控制台也没有报错了！
注意：
配置文件一定认真检查，这是区分大小写的，可能就是哪里没对应上 导致目录找不到 这些问题
最后附上全部配置文件
