Subject [jira] [Created] (HBASE-15232) Exceptions returned over multi RPC don't trigger region location reloads
Date Mon, 08 Feb 2016 18:00:43 GMT
Josh Elser created HBASE-15232:
----------------------------------

             Summary: Exceptions returned over multi RPC don't trigger region location reloads
                 Key: HBASE-15232
                 URL: https://issues.apache.org/jira/browse/HBASE-15232
             Project: HBase
          Issue Type: Sub-task
          Components: Client
            Reporter: Josh Elser
            Assignee: Josh Elser
             Fix For: 2.0.0, 1.3.0, 1.2.1, 1.1.4


Follow-on for HBASE-15221:

A work-around was added in HTableMultiplexer to work around an issue that AsyncProcess wasn't
clearing the region location cache on Exception. This was stemming from the issue that the
{{tableName}} is {{null}} because HTableMultiplexer is using the {{multi}} RPC. This causes
an error that looks like:

{noformat}
[WARN] Coding error, see method javadoc. row=[B@1673eff, tableName=null
{noformat}

HBASE-15221 should fix HTableMultiplexer, but it would be good to push the fix down into AsyncProcess
instead of using higher-level workarounds.
