Subject Re: I have a problem on flume ng.

It seems you are using a custom build of Flume - the type for your sink is
not a FQCN or one of the defined types in SinkType.

It would be helpful if you inform us with the following additional

1. The Flume version you updated for this custom build.
2. The log files in both agents when this error occurred.

This will help out in the diagnosis of the root cause.

If I were to take a wild guess, there are possible errors taking place in
one or both agents.

Also, you are using MemoryChannel which is volatile and non-persistent.

Stoping the agent effectively kills the JVM process and discards any events
that may have been buffered the process memory for this channel.

Any events buffered in the memory channel before the agent was stopped will
be lost permanently.

I personally only use memory channels when doing small tests. I dont use it
in production events where I cannot afford to lose the events captured by
the sources.

I would recommend that you send us your log files, including the version of
Flume NG with a summary of the channels you made for your custom build.

Also, try changing the channel type to FileChannel and see if you still
have this issue when you restart the agents.
