[jira] Created: (HBASE-3378) NullPointerException when decoding
remote exception
NullPointerException when decoding remote exception
---------------------------------------------------
Key: HBASE-3378
URL: https://issues.apache.org/jira/browse/HBASE-3378
Project: HBase
Issue Type: Bug
Components: util
Affects Versions: 0.20.6
Reporter: Ted Yu
Fix For: 0.90.1
We recently saw several occurrences of NPE. Here is one of them:
{noformat}

[jira] [Resolved] (HBASE-3378) NullPointerException when decoding
remote exception
Posted by "stack (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-3378?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
stack resolved HBASE-3378.
--------------------------
Resolution: Cannot Reproduce
Fix Version/s: (was: 0.96.0)
Resolving as can't reproduce. Filed against 0.20.6 and my guess is probably fixed by now.
