I have a cloudera 5.5 (3 nodes)cluster. I am using Impala1.1 for my Queries.
Previously the RAM on 1 machine was 40GB(master node) and other two were 2 GB(datanodes) each. It was taking long to execute queries.
Now i have increased RAM of datanodes to 16GB each but there is no considerable difference in execution time.
Do i need to configure anything for impala to take effect of increased RAM.
Please help me out.
Thanks in Advance
