[jira] Commented: (HADOOP-3664) Remove deprecated methods introduced in changes to validating input paths (HADOOP-3095)

["Tom White (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-3664?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12614715#action_12614715 ] 

Tom White commented on HADOOP-3664:
-----------------------------------

I'm wondering whether we want to remove FileInputFormat#validateInput - is it needed to do job validation (e.g. HADOOP-1683), or would that be better done elsewhere?

Also, FileSystem#getFileBlockLocations(Path, long, long) is actually a convenience method for FileSystem#getFileBlockLocations(FileStatus, long, long), so there's not much harm in leaving it there. It's used quite widely. FileSystem implementations only need to implement the latter signature, so it's not a burden on them.

If we decide not to remove either or both of these methods then we would just undeprecate them.
