--------------------------------------

Yes, I guess we could document this as a known issue in earlier versions.

> 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
