Subject [jira] [Commented] (ACCUMULO-3928) TableNotFoundException triggered by MemoryManager
Date Thu, 02 Jul 2015 20:35:04 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3928?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14612483#comment-14612483

Keith Turner commented on ACCUMULO-3928:
----------------------------------------

bq. I think if we start having more problems, it might be a sign that we need to pass around
the exceptions a bit better.

I like that.

> Marked fixVersion for all versions, under the assumption that it does affect all. Need
to verify. Should catch this case and fail gracefully, making sure that this is an expected
state to even arrive in.
