Hi @apedroso ,   thank you for starting this thread.   In this reply, I will focus on how the YARN RM stores data about historical applications, which can be accessed via the RM Web UI.   The RM keeps data about the applications in its state store [1]. It can be  LeveldbRMStateStore,  FileSystemRMStateStore or ZKRMStateStore.   We recommend using ZKRMStateStore (this is what we use in YARN HA as well), because it is a more robust implementation. For example, you can migrate in RM HA standby RM while the active RM is still running and keep the state-store intact.   Because the RM Web UI is reading the data from the state-store, it is independent of the presence or lack of YARN Application Logs.   What are your exact migration steps? Do I understand correctly that you upgrade your cluster to CDP or do you need to move services to a new cluster, please?   [1] Please read section for "yarn.resourcemanager.store.class" in https://hadoop.apache.org/docs/r3.1.2/hadoop-yarn/hadoop-yarn-site/ResourceManagerRestart.html ...

Hi Experts,   My issue is resolved now. I had raised a ticket with cloudera and they provided my with a modified yumrpm.py file which I replaced with my existing file. This new python had option to skip in case it encounters a blank package. Following are the steps to resolve my issue. 1) verify ambari-agent version is 2.6.2.2 by `ambari-agent --version`  on problematic node   2) stop ambari-agent on problematic node   3)go to /usr/lib/ambari-agent/lib/resource_management/core/providers/package/ ~> cd /usr/lib/ambari-agent/lib/resource_management/core/providers/package/ 4) take bacup of yumrpm.py   ~> mv yumrpm.py /tmp   5) download the attached yumrpm.py and keep it in /user/home/ananya   6) do an diff of ~> diff /tmp/yumrpm.py  /user/home/ananya/yumrpm.py   >>>(diff loooks similar too this) 263,267c263,264 <       if len(name) == 0: <         Logger.info("Skipping installation of empty package") <       else: <         Logger.info("Installing package %s ('%s')" % (name, string_cmd_from_args_list(cmd))) <         self.checked_call_with_retries(cmd, sudo=True, logoutput=self.get_logoutput()) --- >       Logger.info("Installing package %s ('%s')" % (name, string_cmd_from_args_list(cmd))) >       self.checked_call_with_retries(cmd, sudo=True, > logoutput=self.get_logoutput()) <<<<      7) move the yumrpm.py  to /usr/lib/ambari-agent/lib/resource_management/core/providers/package/  mv /user/home/ananya/yumrpm.py  /usr/lib/ambari-agent/lib/resource_management/core/providers/package/   😎 start ambari-agent   Thanks and Regards, Ananya ...

Hello @Mondi ,   thank you for asking for clarification if CDP has a Cloudera Express-like "no license required" distribution. Our licensing strategy changed and you can find the details about it here. For your convenience, I am pasting here a part of the "Subscription Agreement" section that might be relevant for you:   "3. Will Cloudera offer Developer or Trial software Subscriptions? Customers and developers will be able to access our products with a subscription agreement with Cloudera.  We will have partner development subscription agreements for developers through our Cloudera Connect Partner Program, and free (unsupported) short-term trial subscriptions through Cloudera.com."   Based on the documentation Cloudera Express is discontinued from version 6.3.3.   Hope it clarifies, let us know, please!   Kind regards: Ferenc     ...
