Subject [jira] [Commented] (HBASE-13906) Improve handling of NeedUnmanagedConnectionException
Date Mon, 22 Jun 2015 21:37:02 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13906?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14596685#comment-14596685

Sean Busbey commented on HBASE-13906:

looks fine to me. Looks like all IA.Private stuff? If there's some place where these are private
implementations but we're changing behavior a client will see (e.g. when wrapping NUCE in
DNRE) please include a release note.

> One other thing: should we somehow handle NeedUnmanagedConnectionException similarly
to DoNotRetryIOException? It's too late to wire them up thusly, but for the case of bulk load
when the bug is expressed, we go through the full 35x retry loop before eventually failing
the RPC. This would be applicable to branch-1.

> This would apply only to branch-1 as master no longer has unmanaged connections. Probably
we cannot change the inheritance hierarchy due to compatibility guarantees, but maybe we can
do something like everywhere we look for DNRIOE, we do the same for NUCE.
