Cannot cancel a query from CM UI

[ Edited ]

Hey all,

I tried to cancel a query from the cloudera manager UI, but then I got the following error:

  • Error communicating with the Impala Daemon.

Any suggestion how to solve this issue?

Thanks!

Same issue, CM 5.9

But I'm able to terminate through impalad ui directly.

Re: Cannot cancel a query from CM UI

Yeah that is the the most reliable way is to go to the Impala Web UI of the querie's coordinator node.  That would be at a website like:  http://<server_name>:25000/

 

I have seen CM isn't able to stop the Impala queries 100% of the time.  I haven't seen any issues with the Impala Web UI being able to stop a query though.
