Subject [jira] [Commented] (ACCUMULO-2069) ThriftTransportPool too aggressive in closing connections
Date Fri, 03 Jan 2014 01:53:50 GMT

Dave Marion commented on ACCUMULO-2069:
---------------------------------------

I'm also starting to think that this issue is wrapped up in the larger Closeable discussion.
It appears that the ThriftTransportPool closes thrift connections after 3 seconds because
there is no close method on the client objects.

> org.apache.accumulo.core.client.impl.ThriftTransportPool closes unused thrift connections
after 3 seconds of inactivty. This can impact performance by causing tablet server connections
to be constantly torn down and set up. Think of the case where you have a MTBW writer with
a small number of threads and a moderate amount of tservers. Make the timeout configurable.
