We have 4 node cluster of DSE version 2.2.1. The nodes descriptions below,
1 - Cassandra
1 - Cassandra Seed
1 - Analytics Seed
1 - Analytics
We ran a pig script in analytics seed node. We could monitor the MapReduce job through browser(<public_ip>:50030).
The Maps jobs completed 100% and Reduce jobs completed only 23.17% after that its not moving further for so many hours.
The same issue with Hive queries also.
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.
Is there anything need to configure?
Thanks in advance.
