Subject Region Server shutdown automatically
Date Tue, 05 Jan 2010 07:21:57 GMT

We tried to put a few million rows to hbase with 4 region servers(2G RAM),
5 data nodes,
that we found one region server disappeared on the web pages:60010
and tried to get following region server logs.
Anyone can explain what was going on?
