Hi folks,

I am using flume to sink into hbase. I had the set up working
yesterday, but when I restarted my flume agent, it for some reason
cannot dump to hbase anymore (too bad I don't have a version-control
for my config yet.)

Here is the configuration and execution output. The agent essentially
listens for objects via avro and dump to console for debugging and to
hbase. The last portion of the console output shows that an object is
indeed received, but for some reason "scan" on the hbase doesn't show
anything new. I tried Regex/Simple serializer and HBase and
AsyncHbase, none works now...

>From the log I don't see anything obviously wrong. I did a tcpdump on
the agent, and saw it established a couple of connections to the
regionservers, but closed them a few seconds later.

Any info on how to correctly configure this or troubleshoot would be
appreciated.

Thanks!
-Simon

Yeah, now I remembered, I was using Regex serializer...

The comment in the code is actually confusing:
https://github.com/apache/flume/blob/trunk/flume-ng-sinks/flume-ng-hbase-sink/src/main/java/org/apache/flume/sink/hbase/SimpleHbaseEventSerializer.java

It gives me the impression that incrementColumn can be skipped...
