Subject [jira] [Commented] (CASSANDRA-8537) ConcurrentModificationException while executing 'nodetool cleanup'
Date Wed, 07 Jan 2015 04:46:35 GMT

Sebastian Estevez commented on CASSANDRA-8537:
----------------------------------------------

Update, this is happening across multiple nodes and I'm guessing from the stacktrace that
it's related to secondary indexes.

> After adding a new node to an existing cluster (7 already started nodes), and waiting
a few minutes to be sure that data migration to the new node is completed, I began to use
the command nodetool cleanup sequentially on each old node. When I issued this command on
the third node, after a few minutes I got a ConcurrentModificationException.
