@Ananya_Misra  Namenode restart failed with below exception :   'org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /hadoop/hdfs/namenode is in an inconsistent state: previous fs state should not exist during upgrade. Finalize or rollback first.' This issue occurs because, during an upgrade, NameNode creates a different directory layout under NameNode directory, if this is stopped before Finalize upgrade, NameNode directory will go to an inconsistent state. NameNode will not be able to pick the directory with a different layout.   To resolve this issue start Namenode manually through command line with the -rollingUpgrade started option and proceed with the upgrade:   # su -l hdfs -c '/usr/hdp/current/hadoop-client/sbin/hadoop-daemon.sh --config /usr/hdp/current/hadoop-client/conf start namenode -rollingUpgrade started ...

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 ...
