[jira] [Commented] (HIVE-21100) Allow flattening of table subdirectories resulted when using TEZ engine and UNION clause
[ https://issues.apache.org/jira/browse/HIVE-21100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17641987#comment-17641987 ] Arnaud Linz commented on HIVE-21100: The workaround does not always work as sometimes the merge step is skipped, despite having set hive.merge.tezfiles=true; So to be sure we need to add a "hand made" HDFS move after each query with unions to keep the flat directory structure that is necessary for many tools (like Dataiku).

[jira] [Commented] (HIVE-21100) Allow flattening of table subdirectories resulted when using TEZ engine and UNION clause

The motivation is that some systems in Hadoop, like Impala, cannot read directories recursively. If a table was created with Hive with subdirectories and after that, it is queried by Impala, the table will look empty. I know that this patch will only benefit a few people, that's why it is disabled by default and I added an option to turn it on. > Allow flattening of table subdirectories resulted when using TEZ engine and > UNION clause > > > Key: HIVE-21100 > URL: https://issues.apache.org/jira/browse/HIVE-21100 > Project: Hive > Issue Type: Improvement >Reporter: George Pachitariu >Assignee: George Pachitariu >Priority: Minor > Attachments: HIVE-21100.patch > > > Right now, when writing data into a table with Tez engine and the clause > UNION ALL is the last step of the query, Hive on Tez will create a > subdirectory for each branch of the UNION ALL. > With this patch the subdirectories are removed, and the files are renamed and > moved to the parent directory. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
