Subject [jira] [Commented] (YARN-5070) upgrade HBase version for first merge
Date Fri, 10 Jun 2016 23:37:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15325509#comment-15325509

Sangjin Lee commented on YARN-5070:

Thanks for the update [~vrushalic]!

- l.120: From the javadoc, it appears that {{ScannerContext}} keeps track of the progress
towards the limits. But {{nextRaw(List<Cell>)}} creates a new {{ScannerContext}} every
time it is invoked. If the progress should be monitored across multiple invocations of {{nextRaw(List<Cell>)}},
I'm not sure if this will do that. Are we even supposed to create instances of {{ScannerContext}}?
Am I off? I'm basically not sure what is the correct way of using the {{ScannerContext}}.
The same comment goes for {{next(List<Cell>)}}.
- Are we certain that {{batchLimit}} is the correct one to use in {{ScannerContext}}? I also
see {{sizeLimit}} in {{ScannerContext}}.
