Subject Re: HMaster and HRegionServer going down
Date Thu, 06 Jun 2013 05:20:50 GMT
Can you reproduce the problem? if yes,

add the following in your hbase-env.sh

export HBASE_MASTER_OPTS="-verbose:gc -XX:+PrintGCDateStamps
-XX:+PrintGCDetails -Xloggc:$HBASE_LOG_DIR/hmaster_gc.log
$HBASE_MASTER_OPTS"

export HBASE_REGIONSERVER_OPTS="-verbose:gc -XX:+PrintGCDateStamps
-XX:+PrintGCDetails -Xloggc:$HBASE_LOG_DIR/hmaster_gc.log
$HBASE_REGIONSERVER_OPTS"

then, you will got GC log, I just guess this problem was lead with GC.
