Subject [jira] [Commented] (YARN-5070) upgrade HBase version for first merge
Date Thu, 09 Jun 2016 05:33:21 GMT

    [ https://issues.apache.org/jira/browse/YARN-5070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15321920#comment-15321920
] 

Joep Rottinghuis commented on YARN-5070:
----------------------------------------

Perhaps instead of

{code}
int limit = getBatchLimit(scannerContext);
{code}
in #nextInternal(List<Cell> cells, ScannerContext scannerContext)

we should use
{code}
int limit = regionScanner.getBatch();
{code}
See: https://hbase.apache.org/devapidocs/org/apache/hadoop/hbase/regionserver/RegionScanner.html#getBatch%28%29

then we can probably do away with the reflection.
Btw. should we also honor regionScanner.getMaxResultSize()?

> Currently we set the HBase version for the timeline service storage to 1.0.1. This is
a fairly old version, and there are reasons to upgrade to a newer version. We should upgrade
it.
