    [ https://issues.apache.org/jira/browse/CASSANDRA-11701?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15267921#comment-15267921

Stefania commented on CASSANDRA-11701:
--------------------------------------

It seems there was an exception in {{write_rows_to_csv}} that caused {{init_feeding_thread}}
to be called simultaneously by 2 threads. This method should be protected by a lock, here
is the patch:

||2.1||2.2||3.0||trunk||
|[patch|https://github.com/stef1927/cassandra/commits/11701-2.1]|[patch|https://github.com/stef1927/cassandra/commits/11701-2.2]|[patch|https://github.com/stef1927/cassandra/commits/11701-3.0]|[patch|https://github.com/stef1927/cassandra/commits/11701]|
|[dtest|http://cassci.datastax.com/view/Dev/view/stef1927/job/stef1927-11701-2.1-dtest/]|[dtest|http://cassci.datastax.com/view/Dev/view/stef1927/job/stef1927-11701-2.2-dtest/]|[dtest|http://cassci.datastax.com/view/Dev/view/stef1927/job/stef1927-11701-3.0-dtest/]|[dtest|http://cassci.datastax.com/view/Dev/view/stef1927/job/stef1927-11701-dtest/]|

The 2.1 patch merges upwards without conflicts.

After protecting this method, we should be able to see what the initial exception was, [~rhatch]
are you able to run this test a few times on Windows with the patch applied?
