CDH 5.4 Impala webinterface monitoring

avatar
Rising Star

Hi,

 

 

I installed CDH 5.4 and now the manager interface is alerting that the Impala web interface for the catalog server, statestore and daemons are not reachable. They are however up and running. And Impala is also working fine.

 

I have configured the websites to use TLS and this worked find with CDH 5.3

 

right now i have disabled monitoring for the impala web interfaces so the service does not shows up as having trouble.

 

Any ideas on how to fix this?

Good to know.

 

Yes, I believe this can happen if the agents have not been upgraded to CM 5.4. Impala changed the URL from which to fetch metrics in CDH 5.4 the correspondin change to the CM agent is in CM 5.4.

 

Thanks for your help nailing this down.

Hey I'm still facing this issue !
I have CDH 5.4.2 and CM 5.4.1

I verified and the agents are all updated.

 

What else can I do ?

Hi, 

 

we have the same Problem too after upgrading to CDH 5.4.4 and CM 5.4.

the problem is the decimal delimiter 

"max": 0,259594,

 

before upgrading it was a point as delimiter 

\"max\": 1.52533,

that results in a "JSONDecodeError: Expecting property name: line 90 column 19 (char 3162)"

 

how can we fix it?

Hello!

 

I'd guess that you are not in the US, and that you have locale (e.g., LC_ALL) environment variables set.  You're running into https://issues.cloudera.org/browse/IMPALA-2014.  In the meantime, as a workaround, place "LC_ALL=C" into the configuration "Impala Service Environment Advanced Configuration Snippet (Safety Valve)".

 

Please do report back if that works as a workaround for you!

 

Thanks!
