[jira] [Comment Edited] (CASSANDRA-11128) Unexpected exception during request; AssertionError: null

["Russ Hatch (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-11128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15135465#comment-15135465 ] 

Russ Hatch edited comment on CASSANDRA-11128 at 2/6/16 2:17 AM:
----------------------------------------------------------------

easiest way to repro this is using cassandra-dtest (on the dtest branch new_upgrade_classes), something like so:

nosetests -xvs upgrade_through_versions_test.py:ProtoV3Upgrade_2_1_UpTo_3_0_Latest.rolling_upgrade_test

It does not manifest on every attempt, but perhaps 1 in 5 attempts.
