Created table in Hive with dynamic partition enabled..
Adding partition on daily basis
ALTER TABLE test ADD PARTITION (date='2014-03-17') location 's3://test.com/2014-03-05'
Now ,How do I ensure that whether partition added or not ?
show partitions mytable;
Note: if you have more than 500 partitions, you may want to output to a file:
$hive -e 'show partitions mytable;' > partitions
hive> SHOW PARTITIONS partitioned_user; OK country=AU/state=AC country=AU/state=NS country=AU/state=NT country=AU/state=QL country=AU/state=SA
Thanks for your answer, I am looking for kind of API to tell that, partition added or not.. I will be difficult to check the partition status daily and take call when there is a failure. ( Want to automate rather checking it manually)
@Gobi Subramani - How are you creating the partitions? Is there a particular pattern, you will be following.
If yes, you can write a small shell / python script which can call the above command to check if the partition exists. And then you can probably add that to the cron job.
Yes, there is a pattern for creating partition (yyyy-mm-dd) ..
OK,your idea is , run the command and store the result and check for the existence of the partition ?? Is there any other simple way to check ?
