Subject [jira] [Updated] (HIVE-9399) ppd_multi_insert.q generate same output in different order, when mapred.reduce.tasks is set to larger than 1
Date Thu, 29 Jan 2015 22:57:35 GMT

     [ https://issues.apache.org/jira/browse/HIVE-9399?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chao updated HIVE-9399:
-----------------------
    Attachment: HIVE-9399.1-spark.patch

The issue is caused by the "dfs -cat" command which is not handled by {{SORT_QUERY_RESULTS}}.
Here I propose to explicit set the number of reduce tasks in the test file.

is set to larger than 1

> If running ppd_multi_insert.q with {{set mapred.reduce.tasks=3}}, the output order is
different, even with {{SORT_QUERY_RESULTS}}.
