I'm running:
hbase-0.20.6
zookeeper-3.2.2
hadoop-0.20.2
Everything on a single machine as I'm testing out some M/R -> hbase code and
everything on that front is working fine. After a period of inactivity,
however, my log was flooded (millions) of the same 'WARN' message below. Any
ideas on this? I couldn't find this issue anywhere else, and am wondering how
to prevent it or stop the flooding of information (other than turning the
logging off or to a higher level).
Thanks in advance
Mike

And this continues for as long as I let it. Millions of messages.
