-------------------------------------------
Summary: Knox startup attempts fails after Blueprint deployment if
HDFS audit is enabled
Key: AMBARI-23047
URL: https://issues.apache.org/jira/browse/AMBARI-23047
Project: Ambari
Issue Type: Bug
Components: ambari-admin, ambari-server
Affects Versions: 2.5.1
Reporter: Rohit Rai Malhotra
While deploying the Blueprint, the Knox service tries to start up before
HDFS(Namenode), this works fine when HDFS audit is not enabled.
But Ranger policies are implemented with HDFS audit enabled, the Knox startup
fails as Ambari checks for HDFS files & set permission for /ranger/audit etc.
Thus, Ambari needs to handle the case when HDFS audit is enabled but HDFS is
not up during Knox startup
OR
The startup sequence should be changed for Knox to start "after" HDFS.
