In my case I increased the memory and that resolved my issue. </p> http://www.datastax.com/support-forums/topic/pig-and-hive-queries-not-working-in-dse-221#post-8195 Fri, 28 Dec 2012 15:37:20 +0000 Piotr Kołaczkowski 8195@http://www.datastax.com/support-forums/ <p>Are there any errors reported in system.log? E.g about failed tasks?<br /> What is the load on the machines, when the task is "not moving further"?<br /> Especially, have you given enough memory for your reducers? Can you check with jmap that the dse daemon process has enough free heap space? </p> http://www.datastax.com/support-forums/topic/pig-and-hive-queries-not-working-in-dse-221#post-7968 Thu, 13 Dec 2012 13:25:09 +0000 habeebraja 7968@http://www.datastax.com/support-forums/ <p>Hi,</p> <p>We have 4 node cluster of DSE version 2.2.1. The nodes descriptions below,</p> <p>1 - Cassandra<br /> 1 - Cassandra Seed<br /> 1 - Analytics Seed<br /> 1 - Analytics</p> <p>We ran a pig script in analytics seed node. We could monitor the MapReduce job through browser(&lt;public_ip&gt;:50030).</p> <p>The Maps jobs completed 100% and Reduce jobs completed only 23.17% after that its not moving further for so many hours.</p> <p>The same issue with Hive queries also. </p> <p>Note: The process is still running on that machine. The script also not complicated. Just a simple script to dump the records. Pig and Hive not used simultaneously.</p> <p>Is there anything need to configure?</p> <p>Thanks in advance. </p>
