----------------------------------
Summary: AsyncWriter of FSHLog might throw
ArrayIndexOutOfBoundsException
Key: HBASE-11200
URL: https://issues.apache.org/jira/browse/HBASE-11200
Project: HBase
Issue Type: Bug
Components: wal
Affects Versions: 0.98.2
Reporter: cuijianwei
Priority: Minor
AsyncWriter of FSHLog might throw ArrayIndexOutOfBoundsException because of the
following code in AsyncWriter#run():
{code}
}
}
if (!hasIdleSyncer) {
int idx = (int)this.lastWrittenTxid % asyncSyncers.length;
asyncSyncers[idx].setWrittenTxid(this.lastWrittenTxid);
}
}
{code}
In obove code, "this.lastWrittenTxid % asyncSyncers.length" might become
negative when this.lastWrittenTxid is bigger than Interger.MAX_VALUE where
this.lastWrittenTxid is a long. The attachment gives a quick fix.
