[Ambari] Critical Random Alerts: connection failed to IP:PORT

avatar

Hi all,

We've installed an HDP cluster (2.3.4.0-3485) on Azure. All services have been implemented including Ambari (2.2.0.0).

We allo "kerberized" the cluster.

Nevertheless, sometimes some alerts appears mentionning a connection failed with a service (random too) talking about credentials (see screenshot).

After a while, they disappear.

Do you know how can I managed them or best, correct this issue ?

I'd really appreciate for your help.

KR,

Michaël

Thank you @Neeraj Sabharwal for your quick answer.

We have already seen this topic and applied the solution. We also tried with 5m40 but same errors.

To answer to @Artem Ervits, my Java version is oracle jdk1.8.0_60.

I use Ambari 2.2 and I'll se that I've two folders OOZIE on UNIX: 4.0.0.2.0 and 4.2.0.2.3. The modification has been made on the first one 4.0.0.2.0 because in the second one, I do not have the alert_check_oozie_server.py file. In Ambari, it mentions that my OOZIE version is 4.2.0.2.3.

Any advice ?

Many thanks

Thank you very much for your return.

I think we will wait for Ambari 2.2.2 because, now, we understood the alert so it's not really criticial...

Best regards,
