The new API aims to eliminate individual "getFileBlockLocations" calls to NN for each file in the input directory of a job. Instead, a file's block locations are returned together with FileStatus when listing a directory, thus improving getSplits performance. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
