Ralph Romanos created CASSANDRA-4813:
----------------------------------------
Summary: Problem using BulkOutputFormat while streaming several
SSTables simultaneously from a given node.
Key: CASSANDRA-4813
URL: https://issues.apache.org/jira/browse/CASSANDRA-4813
Project: Cassandra
Issue Type: Bug
Affects Versions: 1.1.5, 1.1.3
Environment: I am using SLES 10 SP3, 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
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.
