Subject BulkOutputFormat error - org.apache.thrift.transport.TTransportException
Date Thu, 13 Dec 2012 20:57:19 GMT
Hi

I am a newbie to Cassandra. Was trying out a sample (word count) code on BulkOutputFormat
and got stuck with an error.

What I am trying to do is - migrate all Hive tables (from Hadoop cluster) to Cassandra column
families.
My MR program is configured to run on Hadoop cluster v 0.20.2 (cdh3u3) by pointing job config
params 'fs.default.name' and 'mapred.job.tracker' appropriately.
The output is pointed to my local Cassandra v1.1.7.
Have set the following params for writing to Cassandra:
conf.set("cassandra.output.keyspace", "Customer");
       conf.set("cassandra.output.columnfamily", "words");
       conf.set("cassandra.output.partitioner.class", "org.apache.cassandra.dht.RandomPartitioner");
       conf.set("cassandra.output.thrift.port","9160");    // default
       conf.set("cassandra.output.thrift.address", "localhost");
       conf.set("mapreduce.output.bulkoutputformat.streamthrottlembits", "10");

But, programs fails with the below error:
12/12/13 15:32:55 INFO security.UserGroupInformation: JAAS Configuration already set up for
Hadoop, not re-installing.

Please help me out understand the problem.
