[jira] [Created] (HADOOP-8260) Auto-HA: Replace ClientBaseWithFixes
with our own modified copy of the class
Auto-HA: Replace ClientBaseWithFixes with our own modified copy of the class
----------------------------------------------------------------------------
Key: HADOOP-8260
URL: https://issues.apache.org/jira/browse/HADOOP-8260
Project: Hadoop Common
Issue Type: Test
Components: auto-failover, test
Affects Versions: Auto Failover (HDFS-3042)
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Minor
Attachments: hadoop-8260.txt
The class ClientBaseWithFixes is an attempt to add some workaround code to avoid spurious failures due to ZOOKEEPER-1438. But, even after making those workarounds, I've seen a few Jenkins failures due to that issue. Until ZK fixes this issue, I'd like to just copy the test infrastructure into our own code, and remove the problematic JMXEnv verifications.

[jira] [Updated] (HADOOP-8260) Auto-HA: Replace ClientBaseWithFixes
with our own modified copy of the class
Posted by "Todd Lipcon (Updated) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HADOOP-8260?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Todd Lipcon updated HADOOP-8260:
--------------------------------
Attachment: hadoop-8260.txt
Simple patch. This copy-pastes the class from the ZK 3.4.2 (the one we're depending on). I also removed some of the utility functions that we're not making use of, to minimize the amount of copy-paste.
It's a shame we have to do this, but seems prudent since it may take some time to figure out the underlying ZK bug, and it's only a test issue rather than part of the actual code.
