Maxime Lamothe-Brassard commented on CASSANDRA-7144:
----------------------------------------------------
The writes were not using prepared statements. The batch contain average
INSERT/UPDATEs, but I also have a counter update interleaved between the
statements. Here is a sample:
{code}
self.queries.append( ( ( 'UPDATE met SET n = n + 1 WHERE id = %(id)s', { 'id' :
k } ) )
self.queries.append( ( '''BEGIN UNLOGGED BATCH
INSERT INTO om ( id, obj,
otype ) VALUES ( %(id)s, %(obj)s, %(type)s );
UPDATE loc SET last = %(ts)s
WHERE sid = %(sid)s AND otype = %(type)s AND id = %(id)s;
INSERT INTO lid ( id, sid )
VALUES ( %(id)s, %(sid)s );
APPLY BATCH;''', { 'id' : k,
'obj' :
unicode( obj[ 0 ] ).lower(),
'type' :
obj[ 1 ],
'ts' : ts,
'sid' : ag
} ) )
{code}

> Key: CASSANDRA-7144
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7144
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: Ubuntu 12.04 w/ Oracle JVM, 5 nodes cluster. Nodes 2GB /
> 2 Cores in DigitalOcean.
> Reporter: Maxime Lamothe-Brassard
> Assignee: Tyler Hobbs

> First time reporting a bug here, apologies if I'm not posting it in the right
> space.
> At what seems like random interval, on random nodes in random situations I
> will get the following exception. After this the hinted handoff start timing
> out and the node stops participating in the cluster.
> I started seeing these after switching to the Cassandra Python-Driver from
> the Python-CQL driver.
