Subject [jira] [Updated] (PHOENIX-4165) Do not wait no new memory chunk can be allocated
Date Sat, 09 Sep 2017 00:21:00 GMT


Lars Hofhansl updated PHOENIX-4165:
    Attachment: 4165-4.x-HBase-0.98.txt

4x.0.98 patch.

There seem to be subtle differences between the branches, even there is absolutely not dependencies
on the HBase version. Took quite a while to make a patch.

Very annoying, and quite easy to make mistakes this way.
How are we sure that all master patches are also in 4.x-hbase-0.98.

> 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.
