[jira] [Commented] (IMPALA-1903) Add support for partitions by
timestamp
[ https://issues.apache.org/jira/browse/IMPALA-1903?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16907534#comment-16907534 ]
H. Vetinari commented on IMPALA-1903:
-------------------------------------
Could someone link the reason for "Won't fix" from the dev mailing lists? Otherwise, I'd like to reopen this (or a similar) issue.
(We like impala as a data query engine, and this issue is preventing us from saving the data (thru spark) in the way that's most natural due to being unable to read from Impala).

> Timestamps or some time related parameter is a very common way data is partitioned. At Yahoo almost all the Hadoop ETL data was partitioned this way. This should be on par with nested data types as an important feature for Impala to have.
