Subject [jira] [Commented] (ACCUMULO-1292) Tablet constructor can hang on vfs classloader, preventing tablets from loading
Date Thu, 22 Jan 2015 02:23:35 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1292?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14286813#comment-14286813

Dave Marion commented on ACCUMULO-1292:
---------------------------------------

I will admit that I was distracted trying to help the kids with their homework at the same
time. I will give it another look tomorrow. You might be right, I should hold the read lock
while checking to see if cl is equal to null. The sychronized methods will block each other.
The locks allow concurrent readers, but the write lock blocks all reads.
