Subject [jira] [Commented] (HDFS-13277) Improve move to account for usage (number of files) to limit trash dir size
Date Fri, 23 Mar 2018 17:35:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-13277?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16411761#comment-16411761
] 

Hanisha Koneru commented on HDFS-13277:
---------------------------------------

Thanks for the update Bharat.

I am sorry I missed this earlier. The default value for {{max.blocks}} is being set to the
default value of {{block.invalidate.limit}}. It should be set to the configured value of this
limit instead. Also, in {{hdfs-default.xml}}, we need to mention that if the new parameter
is not set, it would take the value of the parameter {{dfs.block.invalidate.limit}}.

NITs:{color:#3b73af} {color}
 # {color:#3b73af}{{{color}FsDatasetAsyncDiskService# L104}} has "information" twice in the
comment.
 # It might be good to avoid abbreviations in hdfs-default.xml as it would be reflected
in the docs (referring to no for number).

> The trash subdirectory maximum entries. This puts an upper limit on the size of subdirectories
in replica-trash. Set this default value to blockinvalidateLimit.
