CM don't show Impala queries

Sartner — Fri, 16 Sep 2022 09:29:39 GMT

The Cloudera Manager Impala service don't show the queries..

In "Impala Best Practices", all charts shown "NO DATA".

chart library "Impala queries" can not be shown

The CDH & CM version is 5.4.0(installation by path C), Centos6.6

I have reinstalled the CM and all services, the problem still exists.

The CM TimeZone is Error. But in the OS, the time zone is correct.

I don't know how to fix that.

------------

Finally, I fixed the hwclock time, the probem has been solved.

Sartner,

Just to clarify, the correction of the hwclock time resolved all your issues from your post?

Yes.
Our cluster using puppet to sync the time.
And it sync a wrong time every 10 mins.(it will overwirte '/etc/localtime')

Finally, I turned off the puppet time syncronization, and overwrite the '/etc/localtime' to a correct timezone file.

Then the CM impala service will show the queries.
And Impala Best Practices Charts worked well too.
