Yep, that did it. Didn't realize the id's were event id's and not host id's. Used the attributes.HOST_IDS and was able to pull back the information for the host. With this output, I can sort and build alerting off it. Thank you.

Hi Michalis, Thanks for your advice. I have Migrated from Packages to Parcels, Installed 5.4.2 & then upgraded it to 5.5.1 successfully. the following are the links i have followed: http://www.cloudera.com/documentation/enterprise/latest/topics/cm_ig_migrating_packages_to_parcels.html http://www.cloudera.com/documentation/enterprise/latest/topics/install_upgrade_to_cdh55_parcels.html Thanks a Million

The issue is resolved. I replaced the chrony service with the NTP service, according to Michali's recommendation, on all my hosts and all errors stopped. Not only the errors which where explicitely stating "Failed to collect NTP metrics" but also all other errors. Apparently all these errors where somehow related to the inability to collect NTP metrics. Thank you!

In more elaboration, any namespace changes on Active node is recorded by JNs and Standby node reads these edits from these JNs. And Standby node applies them to own namespace and try to be as close to Active node as possible. In failover scenario, SB node reads all edits from JNs before promoting it-self to Active so that there is full-sync before failover occurs. Hope further details help with better understanding.

Hi, Thanks for your reply. Sorry for delay, i was held up with some other tasks. Below is the output of my .../parcels command. But, seems like other service like spark are up and running in the server which is not shown in the .../parcels command. Output of spark when executing clusters/cluster-name/services command is also copied. {

Hi Michalis, Editing the cloudera-scm-agent/config.ini to point to the correct folder and hard_restarting the agents did the trick. Now all binaries are available in /usr/bin. alternatives --display impala-shell points to the right folder. Thank you for your help 🙂
