Subject [jira] [Commented] (HBASE-9885) Avoid some Result creation in protobuf conversions
Date Mon, 04 Nov 2013 16:47:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13812991#comment-13812991

Nicolas Liochon commented on HBASE-9885:

It failed in HBASE-9886 as well, so I think it's not coming from this patch. May be it's HBASE-9855
as well?

It fails locally as well, 25% of the time.

On the good news side, when I run YCSB with 8 clients on a 3 nodes cluster, I don't have any
major GC. If I run the same test w/ the 0.96.0, I've got ~3 per minute...

> We creates a lot of Result that we could avoid, as they contain nothing else than a boolean
value. We create sometimes a protobuf builder as well on this path, this can be avoided.
