---------------------------------------
Summary: Corrupt timestamps crash the server
Key: KUDU-3534
URL: https://issues.apache.org/jira/browse/KUDU-3534
Project: Kudu
Issue Type: Improvement
Reporter: Abhishek Chennaka
Cam across a situation where the tablet server was crashing with the below log
messages:
I1204 03:42:13.302340 124627 maintenance_manager.cc:382] P

..
F1204 03:42:20.046682 124484 compaction.cc:465] Check failed: 0 != ret (0 vs.
0)
The reason behind is that there were two separate delete ops with the same
exact hybrid stamp which is not ideally possible. This was noticed across
multiple replicas in the same server so most likely it is a server specific
issue (probably disk related) while the same replicas in other servers did not
thrown an issue.
