You can configure it through the ConfigHelper.setThriftMaxMessageLength(), can
you execute java code there? (e.q. not only pig queries)

> Key: CASSANDRA-5504
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5504
> Project: Cassandra
> Issue Type: Bug
> Components: Hadoop
> Affects Versions: 1.2.3
> Reporter: Oleksandr Petrov
> Priority: Critical
> Attachments: patch2.diff, patch.diff
>
>
> Currently, when using newer hadoop versions, due to the call to
> next(ByteBuffer key, SortedMap<ByteBuffer, IColumn> value)
> within ColumnFamilyRecordReader, because `key.clear();` is called, key is
> emptied. That causes the StaticRowIterator and WideRowIterator to glitch,
> namely, when Iterables.getLast(rows).key is called, key is already empty.
> This will cause Hadoop to request the same range again and again all the time.
> Please see the attached patch/diff, it simply adds lastRowKey (ByteBuffer)
> and saves it for the next iteration along with all the rows, this allows
> query for the next range to be fully correct.
> This patch is branched from 1.2.3 version.
> Tested against Cassandra 1.2.3, with Hadoop 1.0.3, 1.0.4 and 0.20.2
