Subject [jira] [Commented] (CASSANDRA-11065) null pointer exception in CassandraDaemon.java:195

hemalatha commented on CASSANDRA-11065:
---------------------------------------

I am seeing a similar exception with Cassandra version 2.2.4. I saw this when I dropped keyspace
when a a node was down. Any time I run repair I see the error. With version 2.2.4, how do
I get rid of this error? Even after recreating keyspace the error still remains.

> Running Cassandra 3.0.1 installed from apt-get on debian.
> I had a keyspace called 'tests'. I dropped it. Then I checked some nodes and one of them
still had that keyspace 'tests'. On a node that still has the dropped keyspace I ran:
> nodetools repair tests;
> In the system logs of another node that did not have keyspace 'tests' I am seeing a null
pointer exception:
