Hi, I am trying to do a group by of 2 records only and getting the following error in Pig Stack Trace:
ERROR 1066: Unable to open iterator for alias final_by_sn ... Caused by: java.io.IOException: Couldn't retrieve job. Under <Hadoop_Home>/logs/userlogs/container.. I see few errors like the following for few tasks: Caused by: java.net.SocketTimeoutException: 60000 millis timeout while waiting for channel to be ready for read. ch : java.nio.channels.SocketChannel[connected local=/127.0.0.1:41641 remote=localhost/127.0.0.1:49313] I think there is some issue with the data which is causing this but not sure how to troubleshoot it. Are there any other places I can see the logs? Appreciate any help! Thanks, Joel
