Hi all,
We are using CDH3B4.
The RegionServer containing .META. stopped working under normal load.
The region server process was up, it could be viewed in hbase admin
interface, but the requests, regions, usedHeap, maxHeap metrics were
constant in time and it couldn't be accessed. Other machines continued
working, but the performance was very bad. A huge log was created on the
machine's HDFS. The cluster came back to normal performance when I had
killed the RegionServer.
In regionServer's log we got only a WARNING
(java.nio.channels.ClosedChannelException) cause by the communication
with the client machine. No logs while it was frozen.
Any idea?
Thank you,
Iulia
