Ted Yu commented on HBASE-4749:
-------------------------------

I should have looked at the bottom of https://builds.apache.org/job/PreCommit-HBASE-Build/181//testReport/org.apache.hadoop.hbase.master/TestMasterFailover/testMasterFailoverWithMockedRITOnDeadRS/ :
{code}
2011-11-05 01:06:29,718 ERROR [Thread-953] hbase.MiniHBaseCluster(201): Error starting cluster
java.lang.RuntimeException: Failed construction of RegionServer: class org.apache.hadoop.hbase.MiniHBaseCluster$MiniHBaseClusterRegionServer
...
Caused by: java.io.IOException: Too many open files
	at sun.nio.ch.IOUtil.initPipe(Native Method)
	at sun.nio.ch.EPollSelectorImpl.<init>(EPollSelectorImpl.java:49)
	at sun.nio.ch.EPollSelectorProvider.openSelector(EPollSelectorProvider.java:18)
{code}
I think we should increase ulimit on asf001.sp2.ygridcore.net
