Ankit Jain reassigned PHOENIX-6548: ----------------------------------- Assignee: Ankit Jain > Race condition when triggering index rebuilds as regionserver closes > -------------------------------------------------------------------- > > Key: PHOENIX-6548 > URL: https://issues.apache.org/jira/browse/PHOENIX-6548 > Project: Phoenix > Issue Type: Bug > Affects Versions: 4.14.3, 4.16.1 > Reporter: Geoffrey Jacoby > Assignee: Ankit Jain > Priority: Minor > > On each regionserver our coprocs keep a cache of HConnections with custom > settings (such as short timeouts) for talking to other regionservers. They're > used when coprocs need to make RPCs, such as during index rebuilds. > When a regionserver is closed, these HConnections are closed as well. > However, we've seen in our test pipelines a race condition where we may have > just given out one of the HConnections to a coprocessor, only to have the > connection closed just before it's used. > This will produce an IllegalArgumentException from the HBase Table object, > which (if the index rebuild was caused by a client Scan) will be thrown back > to the client as a DoNotRetryIOException. > In this case we want the client exception to be a normal retriable > IOException, because if they try again after the region comes up again > somewhere else, the Scan will likely succeed. -- This message was sent by Atlassian Jira (v8.3.4#803005)
