Subject [jira] [Created] (AMBARI-6185) Secure cluster: JCE policy files not distributed on non-client hosts.
Date Wed, 18 Jun 2014 14:06:04 GMT
Andrew Onischuk created AMBARI-6185:

             Summary: Secure cluster: JCE policy files not distributed on non-client hosts.
                 Key: AMBARI-6185
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 1.6.1

Looks like code to distribute JCE policy is in before-install hooks
So if no INSTALL task has executed on a host in secure cluster (for agent is security enabled) then JCE policy
will not be distributed and unzipped on that host

Cluster can easily fall in a situation where a host has no client component.
Following are example scenarios

  1. While installing partial set of services with default selection for serviceComponent
allocation to hosts in installer wizard
  2. Adding a new host with slave components but no client components.

This leads to failure of starting serviceComponent that has no client
installed with them on a host in secure cluster.

I discovered this bug while securing a cluster with just HDFS+ZK+STORM
installed. Security wizard start all services failed with ZK quorum check
failure. Once I installed HDFS_CLIENT on all hosts and restarted all services
then all services came up in secure cluster.
