Subject alter partitions on hive external table
Date Mon, 06 Jun 2016 03:02:17 GMT
Hi friends,

I have created partitions on hive external tables. partitions on
datetime/userid/customerId.

now i have to change the order of the partitions for the existing data for
all the dates.

order of the partition is custerid/userid/datetime.

Anyone can help me, how to alter the partitions for the existing table.
Need a help to write a script to change the partions on existing data.
almost 3 months data is there to modify as per new partition so changing
each date is difficult. Any expert can help me.

Thanks
Raj
