Subject [jira] [Commented] (ACCUMULO-3391) MiniAccumuloCluster hangs when add more splits than TServers.
Date Mon, 08 Dec 2014 02:52:13 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3391?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14237381#comment-14237381

Josh Elser commented on ACCUMULO-3391:
--------------------------------------

Assuming that your client was hung on the addSplits method call (which you should verify via
`jstack` or `kill -3 $pid`), what were the master and tablet server doing (stackdump would
also be helpful)? Attach the logs here if you want someone to look at it, please.

There should be no reason why a single tserver can't support 16 splits at once (much less
hundreds of splits).

> When my MAC had one TServer and I tried to add 16 splits, the client program hung. When
my MAC had 20 TServers, the client program worked. I am not 100% sure of this behavior because
I may have changed more than one thing while testing. Would like someone to verify this behavior
please.
