[jira] [Commented] (HIVE-25790) Make managed table copies handle updates (FileUtils)

    [ https://issues.apache.org/jira/browse/HIVE-25790?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17606546#comment-17606546 ] 

Teddy Choi commented on HIVE-25790:
-----------------------------------

I made a pull request. There's its third commit running on Jenkins. It copies the only different files from a source path to a destination path. For existing directories and files, it skips full copies but updates modification times to represent that it's updated. It's most optimized for HDFS-HDFS replication scenarios with checksum, block size, and length comparisons.
