Sahil Takiar commented on HIVE-15121: ------------------------------------- Something seems to be wrong with ptest will try re-attaching patch tomorrow. > Last MR job in Hive should be able to write to a different scratch directory > ---------------------------------------------------------------------------- > > Key: HIVE-15121 > URL: https://issues.apache.org/jira/browse/HIVE-15121 > Project: Hive > Issue Type: Sub-task > Components: Hive > Reporter: Sahil Takiar > Attachments: HIVE-15121.WIP.1.patch, HIVE-15121.WIP.patch > > > Hive should be able to configure all intermediate MR jobs to write to HDFS, > but the final MR job to write to S3. > This will be useful for implementing parallel renames on S3. The idea is that > for a mutli-job query, all intermediate MR jobs write to HDFS, and then the > final job writes to S3. Writing to HDFS should be faster than writing to S3, > so it makes more sense to write intermediate data to HDFS. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
