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 3.1.5 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
