HDP2 to CDP Private Cloud Base Two Stage upgradePDF version

Ranger admin password

During the HDP upgrade, Ranger admin fails to apply the Java patch to change all admin passwords if the hadoop.security.credstore.java-keystore-provider.password-file property is set in core-site.

Before you upgrade from HDP 2.6.5 to HDP intermediate bits, you must manually perform the following steps:
  1. SSH to the ranger admin host
  2. cd /etc/ranger/admin/conf/
  3. vi ranger-admin-env-credstore.sh
  4. add "export HADOOP_CREDSTORE_PASSWORD=none" in the "ranger-admin-env-credstore.sh" file
  5. chown ranger:ranger ranger-admin-env-credstore.sh
  6. chmod 755 ranger-admin-env-credstore.sh
