Same issue with 1.1.6 and Hadoop 1.0.3
I have the following from the Cassandra logs as well

> Key: CASSANDRA-4813
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4813
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 1.1.3, 1.1.5
> Environment: I am using SLES 10 SP3, Java 6, 4 Cassandra + Hadoop
> nodes, 3 Hadoop only nodes (datanodes/tasktrackers), 1 namenode/jobtracker.
> The machines used are Six-Core AMD Opteron(tm) Processor 8431, 24 cores and
> 33 GB of RAM. I get the issue on both cassandra 1.1.3, 1.1.5 and I am using
> Hadoop 0.20.2.
> Reporter: Ralph Romanos
> Labels: Bulkoutputformat, Hadoop, SSTables
>
> The issue occurs when streaming simultaneously SSTables from the same node to
> a cassandra cluster using SSTableloader. It seems to me that Cassandra cannot
> handle receiving simultaneously SSTables from the same node. However, when it
> receives simultaneously SSTables from two different nodes, everything works
> fine. As a consequence, when using BulkOutputFormat to generate SSTables and
> stream them to a cassandra cluster, I cannot use more than one reducer per
> node otherwise I get a java.io.EOFException in the tasktracker's logs and a
> java.io.IOException: Broken pipe in the Cassandra logs.
