-----------------------------------------------------------------
We just started our upgrade of 1.1.7 to 1.2.12, and are seeing this, as well.
It seems related to MigrationManager/MigrationTask where a node is endlessly
looping getting retrieving the following system keyspaces from peers:
schema_columnfamilies, schema_columns, schema_keyspaces. Once the entire
cluster is upgraded, however, this behavior subsides.

> Key: CASSANDRA-6614
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6614
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: ubuntu 12.04
> Reporter: Cyril Scetbon
>
> It happens when we upgrade one node to 1.2.13 on a 1.2.2 cluster
> see http://pastebin.com/YZKUQLXz
> If I grep for only InternalResponseStage logs I get
> http://pastebin.com/htnXZCiT which always displays same account of ops and
> serialized/live bytes per column family.
> When I upgrade one node from 1.2.2 to 1.2.13, for 2h I get the previous
> messages with a raise of CPU (as it flushes and compacts continually) on all
> nodes
> http://picpaste.com/pics/Screen_Shot_2014-01-24_at_09.18.50-ggcCDVqd.1390551670.png
> After that, everything is fine and I can upgrade other nodes without any
> raise of cpus load. when I start the upgrade, the more nodes I upgrade at the
> same time (at the beginning), the higher the cpu load is
