Subject [jira] [Commented] (ACCUMULO-2660) InvocationTargetException during ContinuousIngest
Date Fri, 11 Apr 2014 17:04:16 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2660?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13966786#comment-13966786
] 

Mike Drob commented on ACCUMULO-2660:
-------------------------------------

It still propagates an IOException when that is the underlying cause. In the wrapped RuntimeException
and Error case, we were actively doing the wrong thing, but our current code handles it anyway
(because we continue to do the wrong thing in other places).

{{defineTablet}} is only called from inside of {{write}} of an anonymous {{Writer}} created
in {{TabletServerLogger.defineTablet}}. This {{write}} method is called from {{TabletServerLogger.write}}
(line 275) inside of a {{try}} block that catches {{Exception}} and continues to retry.

In the {{Error}} case, we probably want to stop retrying anyway and let that bubble up, since
it indicates something seriously wrong. We wouldn't be catching it anyway if we were using
a compiled call instead of our reflective one, so there's not a good reason to wrap that.

Good?
