Rakesh R commented on HDFS-12106:
---------------------------------

Thanks [~surendrasingh] for the good work!
It looks like the test cases failures are due to OOME.

Apart from the below minor typos, latest patch looks good to me, +1.

# Typo: {{//set 1 when item is}}, it should be {{//set 0 when item is}}
# Typo: {{+ blockMovementMaxRetry + " retry.}}, it should be {{+ blockMovementMaxRetry + "
retries.}}

> # Make satisfy policy retry configurable.
> Based on [discussion|https://issues.apache.org/jira/browse/HDFS-11965?focusedCommentId=16074338&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16074338]
in HDFS-11965, we can make satisfy policy retry configurable.
> # Change {{dfs.storage.policy.satisfier.low.max-streams.preference}}'s value to {{true}}
and modify the default value to true as well. If user wants equal share then it should be
false, but presently it is true which is not correct. Thanks [~umamaheswararao] for pointing
out this case.
