Subject [jira] [Reopened] (HIVE-2453) Need a way to categorize queries in hooks for improved logging
Date Sat, 17 Sep 2011 00:19:14 GMT

     [ https://issues.apache.org/jira/browse/HIVE-2453?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kevin Wilfong reopened HIVE-2453:
---------------------------------


I have changed my mind.  After further examination, I have noticed that some of these flags
would still not be able to be set accurately without reparsing the query.  For example, queries
involving sort by and order by can become largely indistinguishable in complicated queries,
in particular if the sort by only requires one reducer, from the point of the task/operator
tree.

> We need a way to categorize queries, such as whether or not the include a join clause,
a group by clause, etc., in the hooks.  This will allow for better performance logging.
> Currently the only way I can find is to go through the operators in the tasks, but which
operators are used for the different types of queries may change over time.
