[jira] (HBASE-17572) HMaster: Caught throwable while processing
event C_M_MERGE_REGION (UndeclaredThrowableException)
Andrew Purtell created HBASE-17572:
--------------------------------------
Summary: HMaster: Caught throwable while processing event C_M_MERGE_REGION (UndeclaredThrowableException)
Key: HBASE-17572
URL: https://issues.apache.org/jira/browse/HBASE-17572
Project: HBase
Issue Type: Bug
Affects Versions: 1.3.0
Reporter: Andrew Purtell
Running ITBLL 1B rows against 1.3.0 compiled against Hadoop 2.7.3 with the noKill monkey policy, I see both masters go down with
master.HMaster: Caught throwable while processing event C_M_MERGE_REGION
java.lang.reflect.UndeclaredThrowableException
In ServerManager#sendRegionsMerge we call ProtobufUtil#mergeRegions, which does a doAs, and the code within that block invokes RSRpcServices#mergeRegions, but is not resilient against RegionOpeningException ("region is opening")
An UndeclaredThrowableException is "thrown by a method invocation on a proxy instance if its invocation handler's invoke method throws a checked exception (a Throwable that is not assignable to RuntimeException or Error) that is not assignable to any of the exception types declared in the throws clause of the method that was invoked on the proxy instance and dispatched to the invocation handler." (http://docs.oracle.com/javase/7/docs/api/java/lang/reflect/UndeclaredThrowableException.html)
