Flume启动运行时报错org.apache.flume.ChannelFullException: Space for commit to queue couldn't be acquired. Sinks are likely not keeping up with sources, or the buffer size is too tight解决办法（图文详解）

 

 

 

前期博客

Flume自定义拦截器（Interceptors）或自带拦截器时的一些经验技巧总结（图文详解）

 

 

 

 

问题详情

　　启动agent服务

[hadoop@master flume-1.7.0]$ bin/flume-ng agent --conf conf_MySearchAndReplaceInterceptor/  --conf-file conf_MySearchAndReplaceInterceptor/flume-conf.properties --name agent1  -Dflume.root.logger=INFO,console

 

 

　　我这里，出现了这个错误

　　解决办法

 

 　　

 

 

 

 

agent1.channels.memoryChannel.keep-alive = 60
agent1.channels.memoryChannel.capacity = 1000000

 

 

 　　然后，再来修改

修改java最大内存大小
vi bin/flume-ng
JAVA_OPTS="-Xmx1024m"

 

 

 

 

 

 　　改为

 

 

 　　即，修改后之后，再次运行

[hadoop@master flume-1.7.0]$ bin/flume-ng agent --conf conf_MySearchAndReplaceInterceptor/  --conf-file conf_MySearchAndReplaceInterceptor/flume-conf.properties --name agent1  -Dflume.root.logger=INFO,console

　　上述错误，得以解决了。
