Wilfred Spiegelenburg commented on YARN-6566:
---------------------------------------------
Looking at the feature I think we have two possible problems:
- From a security point I do not think that this is a good idea. The Hive SQL
query could have sensitive information contained in it. There could be names or
details in multiple parts of the query that you do not want to expose. This
feature could thus lead to information disclosure that you can not control.
- Second problem I see here is that the query info could be large which has a
performance impact. Not just for the UI but also for the state store. Queries
can be hundreds of kilobytes and that detail would need to be persisted in the
state store. There have been a number of jiras to implemented and currently
being worked on to decrease the size of the object that is stored in the state
store and this would negate a lot of that work.

> When I tuning the hive HQL in multi-users environment,I can not get the full
> SQL text in hadoop web view,so it is difficult to tuning the SQL.When I try
> to set the SQL text in hadoop job's jobname property,I realize it is going to
> damage the structure of hadoop applications web view,so I add a property to
> hadoop job,which named "jobdescription",When a hive HQL be submitted,the full
> HQL text was assigned to the property,so i can identified the HQL coveniently
