[jira] [Commented] (HBASE-3857) Change the HFile Format
[ https://issues.apache.org/jira/browse/HBASE-3857?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13164613#comment-13164613 ]
Jean-Daniel Cryans commented on HBASE-3857:
-------------------------------------------
Any reason why this patch is removing compaction and flush queue sizes?
{code}
- this.metrics.compactionQueueSize.set(compactSplitThread
- .getCompactionQueueSize());
- this.metrics.flushQueueSize.set(cacheFlusher
- .getFlushQueueSize());
{code}
If it was intentional, there's a bunch of dead code that also needs to be removed like those methods that were called. If it wasn't, meaning there's currently no way in 0.92 to get the compaction queue size, then this would be sufficient for me to kill the RC.
