Dmitriy... I just found out that after 20 mins I get throws errors 2011-03-15 10:52:48,662 [Thread-4-SendThread] INFO org.apache.zookeeper.ClientCnxn - Server connection successful 2011-03-15 11:16:39,186 [Thread-4] INFO org.apache.hadoop.mapred.JobClient - Cleaning up the staging area hdfs://db1/tmp/hadoop-mapred/mapred/staging/cxt/.staging/job_201103080952_0033 2011-03-15 11:16:39,188 [main] INFO org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MapReduceLauncher - job null has failed!
