Hi Anil,
The Free Edition of Cloudera Manager doesn't currently track MR jobs and
Impala queries. Your best bet is to simply time different queries and
compare the results. Impala, typically on port 25000 has a web UI to show
you a query log where you can see query durations.
Note that there are simple things like correctly compressing your data that
help a lot with query performance. Contact the appropriate mailing lists
for Impala and Hive if you're finding that you're getting performance worse
than you expect.
Cheers,
-- Philip
