Yuki Morishita updated CASSANDRA-4813: -------------------------------------- Attachment: (was: 4813.txt) > 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: 1.1.0 > 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 > Assignee: Yuki Morishita > Priority: Minor > Labels: Bulkoutputformat, Hadoop, SSTables > Fix For: 1.2.0 rc1 > > Attachments: 4813.txt > > > 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. -- This message is automatically generated by JIRA.
