Subject [jira] [Commented] (PHOENIX-4165) Do not wait no new memory chunk can be allocated
Date Sat, 09 Sep 2017 04:26:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-4165?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16159726#comment-16159726

Lars Hofhansl commented on PHOENIX-4165:
----------------------------------------

I wonder whether we can hide HBase dependencies in maven modules, the way HBase does it with
its Hadoop dependencies? (anyway, unrelated topic)

> Currently the code waits for up to 10s by fault for memory to become "available".
> I think it's better to fail immediately and the let the client retry rather than waiting
on an HBase handler thread.
> In a first iteration we can simply set the max wait time to 0 (or perhaps even -1) so
that we do not attempt to wait but fail immediately. All using code should already deal with
InsufficientMemoryExceptions, since they can already happen right now,
> In a second step I'd suggest to actually remove the waiting code and config option completely.
