T Jake Luciani created CASSANDRA-9580:
-----------------------------------------
Summary: Carnality check broken during incremental compaction
re-opening
Key: CASSANDRA-9580
URL: https://issues.apache.org/jira/browse/CASSANDRA-9580
Project: Cassandra
Issue Type: Bug
Reporter: T Jake Luciani
Priority: Minor
Fix For: 2.1.7
Attachments: lcstest.yaml
While testing LCS I found cfstats sometimes crashes during compaction
It looks to be related to the incremental re-opening not having metadata.
