Sankar Hariappan updated HIVE-13652:
------------------------------------
Attachment: HIVE-13652.01.patch
Added 01.patch:
- Fixed the partition ordering issue with import/repl load.
- Added a test case to verify the bootstrap and incremental replication for
table with multi-partition-columns. This test will pass in base code as well as
change in order doesn't affect the functionality but impacts performance.
- Added screenshots to show the path for partition data files before and after
the fix.

> Table with multiple dynamic partitions like year,month, day exported using
> "export table" command is imported (using "import table") such a way that
> order of partitions is changed to day, month, year.
> Export DB: Hive 0.14
> Import DB: Hive 1.2.1000.2.4.0.0-169
> Tables created as:
> create table T1
> ( ... ) PARTITIONED BY (period_year string, period_month string, period_day
> string) STORED AS ORC TBLPROPERTIES ("orc.compress"="SNAPPY");
> export command:
> export table t1 to 'path'
> import command:
> import table t1 from 'path'
> HDFS file structure on both original table location and export path keeps the
> original partition order ../year/month/day
> HDFS file structure after import is .../day/month/year
