NPE in FileTxnSnapLog when restarting a cluster
-----------------------------------------------
Key: ZOOKEEPER-1333
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1333
Project: ZooKeeper
Issue Type: Bug
Components: server
Affects Versions: 3.4.0
Reporter: Andrew McNair
I think a NPE was created in the fix for
https://issues.apache.org/jira/browse/ZOOKEEPER-1269
Looking in DataTree.processTxn(TxnHeader header, Record txn) it seems likely
that if rc.err != Code.OK then rc.path will be null.
I'm currently working on a minimal test case for the bug, I'll attach it to
this issue when it's ready.
