Subject [jira] [Updated] (ACCUMULO-1923) Ensure ZK instances closed correctly
Date Tue, 17 Dec 2013 16:03:10 GMT

     [ https://issues.apache.org/jira/browse/ACCUMULO-1923?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bill Havanki updated ACCUMULO-1923:
-----------------------------------

    Description: 
Was: "warning at the end of a MapReduce job"

Ensure that ZK instances are closed where opened across the Accumulo codebase. This is an
expansion of the original ticket scope, whose description is below.

Original Description:

While running the randomwalk tests I saw this at the end of a map/reduce job:

{noformat}
22 16:56:30,583 [client.ZooKeeperInstance] WARN : ZooKeeperInstance being cleaned up without
being closed. Please remember to call close() before dereferencing to clean up threads.
{noformat}

This came just after the warning:

{noformat}
22 16:56:31,742 [sequential.MapRedVerify] DEBUG: Dropping table: sequential_hostname_1385157013877_MR
{noformat}
