[jira] [Commented] (HADOOP-16101) Use lighter-weight alternatives to innerGetFileStatus where possible

    [ https://issues.apache.org/jira/browse/HADOOP-16101?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16763826#comment-16763826 ] 

Sean Mackrory commented on HADOOP-16101:
----------------------------------------

The other detail here is that we don't think we need to do a HEAD at all before doing the actual GET work when reading.

> Discussion in HADOOP-15999 highlighted the heaviness of a full innerGetFileStatus call, where many usages of it may need a lighter weight fileExists, etc. Let's investigate usage of innerGetFileStatus and slim it down where possible.
