[jira] [Commented] (PHOENIX-1672) RegionScanner.nextRaw contract not implemented correctly

    [ https://issues.apache.org/jira/browse/PHOENIX-1672?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14326550#comment-14326550 ] 

Lars Hofhansl commented on PHOENIX-1672:
----------------------------------------

And it might have been my fault, I think I said in the past that locking isn't necessary as long as there is only one caller.

> The nextRaw() contract (per Javadoc) requires the caller to hold a lock on the RegionScannerImpl object. Phoenix' *Aggregate observers do not do that as far as I can see.
> That might accidentally work but it not guaranteed to remain that way.
