[jira] [Commented] (ACCUMULO-3182) WAL repeatedly failed recovery
due to NPE in IT
[ https://issues.apache.org/jira/browse/ACCUMULO-3182?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14151664#comment-14151664 ]
John Vines commented on ACCUMULO-3182:
--------------------------------------
looks like the server went down while the wal header was being written. Guess we need to make the code that reads the header more resilient?

> Haven't ever seen this one before. A replication IT failed -- looking into it, it was because the tserver that came up (after killing the original) failed to complete recovery. The below happened a few times before the test ultimately timed out.
