Client caught in an infinite loop when trying to connect to cached server
locations
-----------------------------------------------------------------------------------
Key: HBASE-727
URL: https://issues.apache.org/jira/browse/HBASE-727
Project: Hadoop HBase
Issue Type: Bug
Components: client, ipc
Reporter: Izaak Rubin
Assignee: Izaak Rubin
Priority: Minor
HbaseRPC, which (to my understanding) is used whenever there is a need to
connect to a server, enters an infinite loop to continually retry the
connection until it succeeds. This makes sense for server-to-server
interaction, but it doesn't necessarily make sense for all client-to-server
interaction.
The problem I first observed was in doing fast restarts of HBase. When I
attempted to reload the UI after a restart, it would infinitely try to
re-contact the cached server location from before the restart. The correct
behavior would be to break out of the loop as soon as possible in situations
like the one above. I think that throwing a RetriesExhaustedException would be
the best way to do this, although if anyone has any suggestions please let me
know.
