Subject [jira] [Commented] (HDFS-12327) Ozone: support setting timeout in background service
Date Tue, 22 Aug 2017 06:43:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12327?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16136399#comment-16136399
] 

Yiqun Lin commented on HDFS-12327:
----------------------------------

Thanks for the review, [~cheersynang]. All the comments make sense to me except this one.
bq. Another nit is can we use int for the timeout instead of long?
We don't need to change the type of timeout I think. Method {{Configuration#getTimeDuration}}
returns the {{long}} type value. If we use {{int}} type for the timeout, that means we will
cast long to int of timeout value each time in subclass of background service. There is also
a risk of losing precision that we do the type cast operation.
Attach the updated patch.
