Hello,
at a particular customer location, we are seeing the following NPE during
startup with Cassandra 2.1.18.

I found https://issues.apache.org/jira/browse/CASSANDRA-10501, but this should
be fixed in 2.1.18.
Is the above log stating that it is caused by a system keyspace related SSTable?
This is a 3 node setup with 2 others running fine. If system table related and
as LocalStrategy is used as replication strategy (to my knowledge), perhaps
simply copying over data for the schema_keyspaces table from another node might
fix it?
Any help appreciated.
Thanks.
Thomas
