Known issue during 7.1.7 SP2 to 7.1.9 upgrade

OPSAPS-68279: When upgrading CDp 7.1.7 SP2 to CDP 719, sometimes the command step DeployClientConfig fails due to the following error:
Error Message:Client configuration generation requires the following additional parcels to be activated:[cdh]
This can be because of the failure of the activation of the 7.1.9 parcels. To verify:
  1. Navigate to the parcels page.
  2. See if the following error is displayed: Error when distributing to <hostname>: Sc file/opt/cloudera/parcels/.flood/CDH-7.1.9-1.cdh7.1.9.p0.43968053-el7.parcel/CDH-7.1. 1.cdh7.1.9.0.43968053-el7.parcel does not exist.
  3. Using the error above, identify the host and ssh into the host by running the command ssh <hostname>.
  4. Navigate to the agent directory by running the command cd /var/log/cloudera-scm-agent.
  5. Find the following pattern in agent log file(s) Exception: Untar failed with return code: 2, with tar output: stdout: [b''], stderr: [b'\ngzip: stdin: invalid compressed data--format violated\ntar: Unexpected EOF in archive\ntar: Unexpected EOF in archive\ntar: Error is not recoverable: exiting now\n'].
  1. If the above exception appears, you must restart the agent on that host by running the command systemctl restart cloudera-scm-agent.
  2. After the agent restarts, click resume to continue with the upgrade.
