Subject Re: Thrift message length exceeded
Date Wed, 10 Apr 2013 23:29:28 GMT
We are using Astyanax in production but I cut back to just Hadoop and Cassandra to confirm
it's a Cassandra (or our use of Cassandra) problem.

We do have some extremely large rows but we went from everything working with 1.1.5 to almost
everything carping with 1.2.3.  Something has changed.  Perhaps we were doing something wrong
earlier that 1.2.3 exposed but surprises are never welcome in production.

to run fine now fail with code compiled against cass 1.2.3 (and work fine if compiled against
1.1.5 and run against the 1.2.3 servers in production).  I'm using the following setup to
configure the job:
