[jira] [Created] (HBASE-20139) NPE in RSRpcServices.get() when
getRegion throws an exception
Abhishek Singh Chouhan created HBASE-20139:
----------------------------------------------
Summary: NPE in RSRpcServices.get() when getRegion throws an exception
Key: HBASE-20139
URL: https://issues.apache.org/jira/browse/HBASE-20139
Project: HBase
Issue Type: Bug
Affects Versions: 1.3.1
Reporter: Abhishek Singh Chouhan
Assignee: Abhishek Singh Chouhan
Fix For: 1.3.2, 1.5.0, 1.4.3
We can get a NPE in RsRpcServices at
{code:java}
} finally {
if (regionServer.metricsRegionServer != null) {
regionServer.metricsRegionServer.updateGet(
-> region.getTableDesc().getTableName(), EnvironmentEdgeManager.currentTime() - before);
}
if (quota != null) {
quota.close();
}{code}
when region itself is null which might happen when getRegion throws an exception, this is then sent back to the client which is not able to handle this/make sense of it.
{code:java}

This has been fixed by [~stack] over at HBASE-18946 for master, backporting the same to branch-1, 1.3 and 1.4
