null pointer exception in CassandraDaemon.java:195

    Details

    • Severity:
      Low

      Description

      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:

      The error appears every time I run:
      nodetools repair tests;

      I can see it in the logs of all nodes, including the node on which I run the repair.
