NPE out of HRS.run at startup when clock is out of sync
-------------------------------------------------------
Key: HBASE-3261
URL: https://issues.apache.org/jira/browse/HBASE-3261
Project: HBase
Issue Type: Bug
Reporter: Jean-Daniel Cryans
Fix For: 0.90.0, 0.92.0
This is what I get when I start a region server that's not properly sync'ed:
{noformat}
Exception in thread "regionserver60020" java.lang.NullPointerException
at
org.apache.hadoop.hbase.regionserver.HRegionServer.run(HRegionServer.java:603)
at java.lang.Thread.run(Thread.java:637)
{noformat}
I this case the line was:
{noformat}
hlogRoller.interruptIfNecessary();
{noformat}
I guess we could add a bunch of other null checks.
The end result is the same, the RS dies, but I think it's misleading.
