Impala Catalogue server down after upgrading from 5.11.0 to 5.11.1

desind — Fri, 16 Sep 2022 11:54:05 GMT

We have upgraded to 5.11.1 and now we are not able to run any impala queries.

Error:

Query: show databases

We are facing the same issue. Any help?

Re: Impala Catalogue server down after upgrading from 5.11.0 to 5.11.1

desind — Sat, 08 Jul 2017 12:00:11 GMT

We currently identified this issue with the impala certificate. we are now looking into it.

1. Check cert

openssl s_client -connect $hostname:$port -CAfile /abc/hadoop/cloudera-certs/impala-SAN.pem

2. Run hostname -f (This must give you the FQDN)

Re: Impala Catalogue server down after upgrading from 5.11.0 to 5.11.1

mbigelow — Sat, 08 Jul 2017 16:45:26 GMT

I think a new "feature" was added in this latest release. We hit the same issue. We have SSL enabled for Impala with Kerberos. SSL worked for other services like the UIs and Impalad subscribing to the statestore, but catalogd continued to fail to subscribe to the statestore with the same error.

Cloudera Support kindly pointed out that it wasn't trying to communicate using the FQDN; just the hostname. They provided this information. We applied the change and Impala is operational again.

mbigelow — Sat, 08 Jul 2017 16:49:43 GMT

I did this test and I was able to connect to both the statestore and catalogd over SSL, but this was because I was using the FQDN (hostname -f). The issue is that CatalogD and the Statestore are using the short name post upgrade for the statestore subscription. This feels like a bug was introduced or possible this was the intended behavior and it was "fixed", but now you need this configuration setting to get SSL for Impala to work.

Cloudera please fix the code or update the Impala SSL docs to reflect the need for this setting.

@mbigelow - Thank you for keeping the JIRA updated - I'm glad you found the solution through support. It looks like you are hitting a bug in CM and we are working on fixing it. I will reach out to our documentation team to point out this issue in the docs and the release notes of 5.11.1. I'm sorry for the troubles this has caused you.

Re: Impala Catalogue server down after upgrading from 5.11.0 to 5.11.1

Lars Volker — Sat, 08 Jul 2017 19:24:23 GMT

After more investigation I found that this is already documented as a Known Issue in CM: Known Issues and Workarounds in Cloudera Manager 5

For Impala I opened IMPALA-5631 to explain the problem and possible solutions in the docs.

Re: Impala Catalogue server down after upgrading from 5.11.0 to 5.11.1

mbigelow — Sat, 08 Jul 2017 19:49:28 GMT

@Lars Volker Thanks for adding this bit of info. I was looking at IMPALA-5631 as a suspect but never thought to look at CM.

Lesson Learned: pay as much attention to CM release notes as I do CDH release notes.

@desind Could you let me know the details of the Operating system things like Version , name kernel version .

Curious to know .

Re: Impala Catalogue server down after upgrading from 5.11.0 to 5.11.1

desind — Sun, 09 Jul 2017 23:52:09 GMT

After looking at https://www.cloudera.com/documentation/enterprise/release-notes/topics/cm_rn_known_issues.html#concept_xnw_cb4_j1b

To workaround this issue, upgrade to one of the following versions of Cloudera Manager before upgrading CDH:

5.10.2
5.8.6

It does not mention 5.11.1 . so does this issue surface when using CM 5.11.1 ?

Re: Impala Catalogue server down after upgrading from 5.11.0 to 5.11.1

mbigelow — Mon, 10 Jul 2017 00:07:42 GMT

@desind

No. It was kind of always there but the Impala JIRA mentioned above that fixed a issue caused it to pop up. Those CAM releases have the CM fix to have it communicate with the FQDN. For whatever reason it didn't make it into CM 5.11.1. It should be in a CM 5.11 release in the future.

In short either upgrade to one of those CM versions or use the --hostname setting for CM/CDH 5.11.1.

Ok thanks for confirming.

Once we made that change and restarted impala we saw another issue.

We added --hostname=cba24uu.abc.cdb.com to the below two settings and restarted impala.
