Date Mon, 28 Nov 2016 18:29:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15702726#comment-15702726

Rakesh R commented on HDFS-10885:

Thanks [~zhouwei] for the good work. I'm +1 for the latest patch after addressing the below

# Could you mention the default behavior in hdfs-default.xml something like,
If true, enables StoragePolicySatisfier. By default, StoragePolicySatisfier is enabled.
# Few minor [checkstyle warnings|https://builds.apache.org/job/PreCommit-HDFS-Build/17673/artifact/patchprocess/diff-checkstyle-hadoop-hdfs-project.txt]
reported, please take care.
# Just a suggstion. Its good practice to give message. Probably can use like below,
Assert.assertFalse("SPS should not start when a Mover instance is running", active);

[~umamaheswararao], could you please let me know your views about the necessity of [double
checks ensuring that SPS/Mover is not running together|https://issues.apache.org/jira/browse/HDFS-10885?focusedCommentId=15648191&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15648191],
