[jira] [Commented] (IMPALA-6686) Change the DESCRIBE DATABASE
output to look more like Hive output
[ https://issues.apache.org/jira/browse/IMPALA-6686?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17205636#comment-17205636 ]
Csaba Ringhofer commented on IMPALA-6686:
-----------------------------------------
I have kept the current multi-row output when adding managedlocation in https://gerrit.cloudera.org/#/c/16529/2
My plan is to add a query option in another commit that can switch between the current solution and one that uses exactly the same output as Hive. The current solution can be potentially deprecated in the future. Creating this switch seems smaller work than handling the potential issues coming from breaking tools rely on the current output.
