-------------------------------------
Status: Patch Available (was: Open)
> Configuration Symlink Is Incorrect After Stack Distribution
> -----------------------------------------------------------
>
> Key: AMBARI-21188
> URL: https://issues.apache.org/jira/browse/AMBARI-21188
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 3.0.0
> Reporter: Jonathan Hurley
> Assignee: Jonathan Hurley
> Priority: Critical
> Fix For: 3.0.0
>
>
> The configuration symlinks for a component after installation should reflect something similar to the following:
> /etc/component/conf -> /usr/hdp/current/component/conf
> /usr/hdp/current/component/conf -> /etc/component/<version>/conf
> For example:
> {noformat}
> [root@c6403 ~]# ll /etc/zookeeper/
> total 12
> drwxr-xr-x 3 root root 4096 Jun 5 20:19 2.4.2.0-236
> drwxr-xr-x 3 root root 4096 Jun 5 20:38 2.6.0.0-334
> lrwxrwxrwx 1 root root 26 Jun 5 20:38 conf -> /usr/hdp/current/zookeeper-server/conf
> drwxr-xr-x 2 zookeeper hadoop 4096 Jun 5 20:17 conf.backup
> [root@c6403 ~]# ll /usr/hdp/current/zookeeper-server/conf
> lrwxrwxrwx 1 root root 28 Jun 5 20:38 /usr/hdp/current/zookeeper-server/conf -> /etc/zookeeper/2.6.0.0-334/0
> {noformat}
> This is the way that the structure exists after a normal installation today. However, it seems that distribution a new stack breaks this:
> {code}
> [root@c6403 zookeeper]# ll /etc/zookeeper/
> total 12
> drwxr-xr-x 3 root root 4096 Jun 5 20:19 2.4.2.0-236
> drwxr-xr-x 3 root root 4096 Jun 5 20:38 2.6.0.0-334
> lrwxrwxrwx 1 root root 26 Jun 5 20:38 conf -> /etc/zookeeper/conf.backup
> drwxr-xr-x 2 zookeeper hadoop 4096 Jun 5 20:17 conf.backup
> {code}
> The {{conf}} symlink is now pointing to {{conf.backup}} which is the interim temporary location.
