Subject [jira] [Commented] (HDFS-9089) Balancer and Mover should use ".system" as reserved inode name instead of "system"
Date Sat, 19 Sep 2015 15:59:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9089?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14877190#comment-14877190
] 

Surendra Singh Lilhore commented on HDFS-9089:
----------------------------------------------

bq. If it is configurable, then it is possible to run two balancers at the same time by running
them with two different (mis-configured) conf values.

Correct... :)

As per defect description
bq. This folder created is not deleted once mover or balancer work is completed

Do we need to fix this ?

> This folder created in not deleted once mover or balancer work is completed So user cannot
create dir "system" .
> Its better to make ".system" as reserved inode for balancer and mover instead of "system".
