> Starting approximately with commit c2812f3 (the January 3rd nightly build by DataStax Jenkins, #669), a few of the pycassa unit tests related to multigetting a particular supercolumn started failing periodically.  The nightly build is against Cassandra trunk.
> You can reproduce with the pycassa unit tests fairly easily:
> {noformat}
> nosetests tests/test_columnfamily.py:TestSuperColumnFamily.test_multiget_supercolumn
> {noformat}
> It should fail within a few runs.
> It looks like one of the requested keys isn't being returned at all.
