Nick Dimiduk commented on HBASE-10643: -------------------------------------- Presumably, yes. There's a JvmPauseMonitor log in proximity to BlockCache initiation. > Failure in RS when using large size bucketcache > ----------------------------------------------- > > Key: HBASE-10643 > URL: https://issues.apache.org/jira/browse/HBASE-10643 > Project: HBase > Issue Type: Bug > Components: regionserver > Affects Versions: 0.98.0, 0.96.0 > Reporter: Biju Nair > Labels: bucketCache, regionserver > > When RS is brought up with XX:MaxDirectMemorySize of 22GB or higher, RS fails > after a successful start. From the RS logs it looks like the bucketCache > memory allocation is taking more time makes the RS considered dead by ZK. One > option to fix the problem would be to allocate the bucketCache before > registering with ZK. > 2014-02-28 18:54:42,967 WARN [regionserver60020.compactionChecker] > util.Sleeper: We slept 33496ms instead of 10000ms, this is likely due to a > long garbage collecting pause and it's usually bad, see > http://hbase.apache.org/book.html#trouble.rs.runtime.zkexpired > 2014-02-28 18:54:42,967 WARN [regionserver60020.periodicFlusher] > util.Sleeper: We slept 33496ms instead of 10000ms, this is likely due to a > long garbage collecting pause and it's usually bad, see > http://hbase.apache.org/book.html#trouble.rs.runtime.zkexpired > 2014-02-28 18:54:42,967 WARN [JvmPauseMonitor] util.JvmPauseMonitor: > Detected pause in JVM or host machine (eg GC): pause of approximately 23988ms > GC pool 'ParNew' had collection(s): count=1 time=24432ms > 2014-02-28 18:54:43,006 FATAL [regionserver60020] regionserver.HRegionServer: > ABORTING region server bbg-master2.bbg-test.hdp,60020,1393628951236: > org.apache.hadoop.hbase.YouAreDeadException: Server REPORT rejected; > currently processing bbg-master2.bbg-test.hdp,60020,1393628951236 as dead > server > at > org.apache.hadoop.hbase.master.ServerManager.checkIsDead(ServerManager.java:341) > at > org.apache.hadoop.hbase.master.ServerManager.regionServerReport(ServerManager.java:254) -- This message was sent by Atlassian JIRA (v6.2#6252)
