Query monitoring errors after CDH 5.10 upgrade

Hi
I recently upgraded one of our cluster from CDH 5.8.3 to CDH 5.10.2.
After upgrade, impala started giving below critical warnings.
Even though the applications are running fine, i keep on getting emails with when ever there is an error.
All the queries and applications are the same before the upgrade and i wasn't getting any of these errors earlier.
I tried to ignore these errors by increasing the threshold for messages. But the errors just keep on increasing.
Any thoughts?

Error message:
Query Monitoring Status
There are 4 error(s) seen monitoring executing queries, and 0 errors(s) seen monitoring completed queries for this role in the previous 15 minute(s). Critical threshold: 2.

Logs from the impala daemon which got the above error.
Nov 6, 1:20:33.531 PM INFO status.cc:114

Re: Query monitoring errors after CDH 5.10 upgrade

HI Abhishek,

The log message you posted for Impala does not seem like an ERROR, it was INFO log, are you sure this was related to the warning you get from CM?

Are you able to check the exact error reported in CM's interface?

Re: Query monitoring errors after CDH 5.10 upgrade

Below is the only error message i see.

Turns out that query was running through python and parsing some of the columns while inserting.

This didn't gave error before upgrade.
