Customer able to see the Request pool related information CDH5.12, later it was removed due to https://issues.apache.org/jira/browse/IMPALA-5598.
Now, we can able to view the request pool related information for the query in Co-ordinator dameon (impala daemon WebUI) /memz page. Here we can see only the current memory usage of the request pool. If we need to see th request pool relted info for a query that was executed before 4or6 hours, it is not possible.
Shall have this request enabled in Impala daemon webUI/memz page, so that we can go back in time to see information related to Request pool memory in impala (say last 24 hours)
