Subject [jira] [Commented] (CASSANDRA-8281) CQLSSTableWriter close does not work
Date Wed, 07 Jan 2015 13:12:35 GMT


Benjamin Lerer commented on CASSANDRA-8281:

In the latest 2.1 the prepared statement eviction thread is not a problem anymore as it is
now a daemon thread. 
Due to some change in the code, what is now preventing the application to stop is the commit
log threads as specified into CASSANDRA-8572.

The quick fix for this problem is to shutdown the {{CommitLog}} in the close method of {{CQLSSTableWriter}}.

An other problem is that if {{Config.setClientMode(true)}} is used, the code will not work
anymore for the latest 2.0 and 2.1 ({{setClientMode}} has been removed on trunk). By consequence,
I will also have to remove the previous fix for this ticket.

> I called CQLSSTableWriter.close(). But the program still cannot exit. But the same code
works fine on Cassandra 2.0.10.
> It seems that CQLSSTableWriter cannot be closed, and blocks the program from exit.
