----------------------------------
Summary: Scanner retry behavior with RPC timeout on next() seems
incorrect
Key: HBASE-5974
URL: https://issues.apache.org/jira/browse/HBASE-5974
Project: HBase
Issue Type: Bug
Components: client, regionserver
Affects Versions: 0.92.1, 0.90.7, 0.94.0, 0.96.0
Reporter: Todd Lipcon
Priority: Critical
I'm seeing the following behavior:
- set RPC timeout to a short value
- call next() for some batch of rows, big enough so the client times out before
the result is returned
- the HConnectionManager stuff will retry the next() call to the same server.
At this point, one of two things can happen: 1) the previous next() call will
still be processing, in which case you get a LeaseException, because it was
removed from the map during the processing, or 2) the next() call will succeed
but skip the prior batch of rows.
