[jira] [Created] (CASSANDRA-13176) DROP INDEX seemingly doesn't
stop existing Index build
Soumya Sanyal created CASSANDRA-13176:
-----------------------------------------
Summary: DROP INDEX seemingly doesn't stop existing Index build
Key: CASSANDRA-13176
URL: https://issues.apache.org/jira/browse/CASSANDRA-13176
Project: Cassandra
Issue Type: Bug
Components: Compaction, CQL
Environment: CentOS Linux, JRE 1.8
Reporter: Soumya Sanyal
There appears to be an edge case with secondary indexes (non SASI). I originally issued a CREATE INDEX on a column, and upon listening to advice from folks in the #cassandra room, decided against it, and issued a DROP INDEX.
I didn't check the cluster overnight, but this morning, I found out that our cluster CPU usage was pegged around 80%. Looking at compaction stats, I saw that the index build was still ongoing. We had to restart the entire cluster for the changes to take effect.
Version: 3.9
