Subject [jira] [Commented] (HIVE-14270) Write temporary data to HDFS when doing inserts on tables located on S3
Date Thu, 21 Jul 2016 23:27:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14270?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15388609#comment-15388609

Sergio Peña commented on HIVE-14270:
------------------------------------

Only requirement on this patch is the scratch directory is not on S3, or we will end up having
the same slow performance than without the patch.

> Currently, when doing INSERT statements on tables located at S3, Hive writes and reads
temporary (or intermediate) files to S3 as well. 
> If HDFS is still the default filesystem on Hive, then we can keep such temporary files
on HDFS to keep things run faster.
