Recently I tried to add a partition to a hive table with S3 as the storage. The command I tried is given below.

ALTER table mytable ADD PARTITION (testdate='2015-03-05') location 's3a://XXXACCESS-KEYXXXXX:XXXSECRET-KEYXXX@bucket-name/DATA/mytable/testdate=2015-03-05';

I got the following exceptions

Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.SentryFilterDDLTask. MetaException(message:Got exception: org.apache.hadoop.fs.FileAlreadyExistsException Can't make directory for path 's3a://XXXACCESS-KEYXXXXX:XXXSECRET-KEYXXX@bucket-name/DATA/mytable' since it is a file.) (state=08S01,code=1)

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException(message:s3a://XXXACCESS-KEYXXXXX:XXXSECRET-KEYXXX@bucket-name/DATA/mytable/testdate=2015-03-05 is not a directory or unable to create one)

Solution:

Use S3n instead of S3a. It will work. So the S3 url should be

s3n://XXXACCESS-KEYXXXXX:XXXSECRET-KEYXXX@bucket-name/DATA/mytable/testdate=2015-03-05
