Hi, I am currently running 2.5.5 HDP. I am RM HA enabled. When the rm switch from active to inavtive, the jobs are getting stuck and not proceeding further. I tried looking for all the required parameters and everything is set. Can anyone please suggest what is the path forward. Thanks, Bipin

@Ramakrishna Pratapa Thank you for your response. I already have a cluster running with 2.2 and now I upgraded to 2.4. Is it possible to remove ambari completely and install newly for an existing cluster? Can you please point me to the steps.

@Ramakrishna Pratapa Did the upgrade go smoothly? Were you able to upgrade by skipping the consistency check. I am hitting the same problem. Can you please suggest the path forward?

@apappu @apatel I searched and found that this is a know issue https://docs.hortonworks.com/HDPDocuments/Ambari-2.4.0.1/bk_ambari-release-notes/content/ambari_relnotes-2.4.0.1-known-issues.html. I skipped the database check. But I am worried about the upgrade
