Phabricator updated HIVE-2478:
------------------------------
Attachment: HIVE-2478.D927.1.patch
khorgath requested code review of "HIVE-2478 [jira] Support dry run option in
hive".
Reviewers: JIRA
Adding a hive.dry.run parameter that takes the following values :
{off,parse,analyze,plan}
They have the following behaviours:
off : Nothing special, run query as expected
parse : Return after parse finishes (acts as a syntax check)
analyze : Return after semantic analysis finishes
plan : Return after plan generation.
Hive currently doesn't support a dry run option. For some complex queries we
just want to verify the query syntax initally before running it. A dry run
option where just the parsing is done without actual execution is a good option.
