[jira] [Created] (CASSANDRA-11962) Non-fatal NPE during concurrent
repair check
Robert Stupp created CASSANDRA-11962:
----------------------------------------
Summary: Non-fatal NPE during concurrent repair check
Key: CASSANDRA-11962
URL: https://issues.apache.org/jira/browse/CASSANDRA-11962
Project: Cassandra
Issue Type: Bug
Reporter: Robert Stupp
Priority: Minor
"Usual" checks for multiple repairs result in this exception in the log file:
{code}
ERROR [ValidationExecutor:6] 2016-06-06 07:56:23,530 CassandraDaemon.java:222 - Exception in thread Thread[ValidationExecutor:6,1,main]
java.lang.RuntimeException: Cannot start multiple repair sessions over the same sstables

{code}
However, I saw this one:
{code}

Looks like there is no entry for {{cfId}} in {{getActiveSStables}} at {{for (SSTableReader sstable : columnFamilyStores.get(cfId).getSSTables())}}.
(against trunk)
