Amey commented on AMBARI-13870:
-------------------------------

Ambari 2.1.2 does not identify the disk tags. You need to patch the alert script to identify the tags. This issue is resolved in latest ambari.

>          Issue Type: Bug
>          Components: alerts, ambari-agent

> In hdfs-site.site, set DataNode directories to path with storage policy, like
> [DISK] /hadoop/data/sda/data01, [DISK] /hadoop/data/sdb/data02
> But the HDFS will show critical alert about :
> DataNode Unmounted Data Dir
> Data dir(s) not found: [DISK] /hadoop/data/sda, [DISK] /hadoop/data/sdb
> Check /var/lib/ambari-agent/data/datanode/dfs_data_dir_mount.hist file
> It exists, and only show 
>  /hadoop/data/sda/data01,/hadoop/data/sda
>  /hadoop/data/sdb/data02,/hadoop/data/sdb
> But if I remove tag [DISK], the alert will disappear.
> So, dose something wrong for check mount point logic?
