[jira] [Comment Edited] (CASSANDRA-12012) CQLSSTableWriter and
composite clustering keys trigger NPE
[ https://issues.apache.org/jira/browse/CASSANDRA-12012?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15336113#comment-15336113 ]

------------------------------------------------------------------
[~pierz] I was working on some related issue (unset values), thought there might be some intersection.
It seems that in provided code keyspace is not initialised and the {{DatabaseDescriptor#getFlushWriters}} throws NPE. Maybe [this|https://github.com/apache/cassandra/blob/cassandra-3.0/test/unit/org/apache/cassandra/io/sstable/CQLSSTableWriterTest.java#L54-L56] will help you (in test, the server is initialised prior to creating the writer).
