Phabricator updated HIVE-2825:
------------------------------

    Attachment: HIVE-2825.D1995.1.patch

kevinwilfong requested code review of "HIVE-2825 [jira] Concatenating a partition does not
inherit location from table".
Reviewers: JIRA

  https://issues.apache.org/jira/browse/HIVE-2825

  When merging a partition the location is recreated using the scheme and authority of the
table's URI, so if the table's default dfs has changed, the partition's location will as well.
 As part of this I noticed that the auto stats gather configuration variable was being ignored
for merge, so I added this as well.

  When a table is created in one dfs, a partition is added to that table, the table's dfs
is changed, and the partitioned is concatenated, the partitions location remains exactly the
same.  Instead, it should inherit its location from the table, and be updated accordingly.

  See https://issues.apache.org/jira/browse/HIVE-1707 for an analogous change to insert overwrite.
