Hi, I am running a four node instance of CHD on AWS(m1.mediums). We are running into some very odd behaviour that I am hoping someone can help me troubleshoot. We have imported some data into hive using a few different methods(Sqoop, and direct import), And we then connecting Hive to an instance of JaserSoft, to run build some basic reports. Everything works fine for a period of a few hours(4-6) then the connections to Hive start to fail, for no reason that I can see. I have tried looking through what logs I see, but nothing is jumping out at me. I am seeing a number of logs that look like this: /var/log/hadoop-0.20-mapreduce/history/done/ip-10-139-5-19.ec2.internal_1391232018142_/2014/02/02/000000# less job_201402010520_0032_1391311952515_root_select+count%28\*%29+as+trp_erro...error_code%3D203%28Stage but the test in them doesn't indicate any problems. I am very new to the Hadoop world, so forgive me if this is a simple issue, but can anyone give me any hints at how I might troubleshoot this issue? I have rebuilt the entire cluster from scratch once already, so I know this must be some sort of configuration issue. We are running the laster CDH instance, I started the thrift server in the ubunut home directory using: hive --service hiveserver -p 10000 & Thanks Andrew
