ASF subversion and git services commented on ACCUMULO-1379: ----------------------------------------------------------- Commit 79d686faa1e477b9cbd80c6f833ece402050b490 in branch refs/heads/1.5.1-SNAPSHOT from [~busbey] [ https://git-wip-us.apache.org/repos/asf?p=accumulo.git;h=79d686f ] ACCUMULO-1858 Backport ZooKeeper clean up to 1.4 and 1.5. Fix cherry picks two commits: ACCUMULO-1379 - Adding close() to Instance to assist in freeing up resources (cherry picked from commit 7da1164d87227960d3e0cfc841f753067e2c0304) Reason: bugfix Author: John Vines <jvi...@gmail.com> Differs from original by path changes and leaving out ConditionalWriterTest, which is only in 1.6.0+ ---- ACCUMULO-1379 Fix edge cases if error in closing ZooKeeperInstance (cherry picked from commit 3f6c66ede52cb1fb5a122d7bad06d7978ff0a671) Reason: bugfix Author: Christopher Tubbs <ctubb...@apache.org> Signed-off-by: Bill Slacum <ujustgotbi...@apache.org> > PermGen leak > -------------- > > Key: ACCUMULO-1379 > URL: https://issues.apache.org/jira/browse/ACCUMULO-1379 > Project: Accumulo > Issue Type: Bug > Components: client > Affects Versions: 1.4.3, 1.5.0 > Environment: Linux/JBoss > Reporter: Mike Giordano > Assignee: John Vines > Fix For: 1.6.0 > > Attachments: ACCUMULO-1379.patch, ACCUMULO-1379_v2.patch, > ACCUMULO-1379_v3.patch > > > Under version 1.3.7 we are using the following code to initialize a cloudbase > connection during initialization of our web app: > ZooKeeperInstance instance = new > ZooKeeperInstance(instanceName, zooKeepers); > connector = instance.getConnector(userId, > password.getBytes()); > The problem is that under the hood, this call creates several threads that > are not cleaned up when the app is undeployed in JBoss. This is occurring > without performing any scans or interacting with cloudbase in any other way. > After relatively few redeploys of the app, the PermGen Space is OOM. > I can't find any reference in the cloudbase API akin to a close() method for > the Connector object. This is a classloader leak effecting any webapp that is > accessing cloudbase directly. The result of this leak is not simply orphaned > threads, but thousands of classes not gc'd because the classloader itself > can't be gc'd. This is what is filling up PermGen. -- This message was sent by Atlassian JIRA (v6.1#6144)
