Hive ORC bucketed performance issue

[ Edited ]

Hi All,

 

I have created a ORC format table with bucketing on key column. But since the tables are interacted through the UI, many users might be accessing it in parallel that causes the background YARN job to go in ACCEPTED state till YARN frees up some resource. I need to minimize this behavior.

 

I have tried index tried to tweak some settings to increase parallel threads but still it is not working out. It is very much important to me.

 

Can anyone help on this. Thanks in Advance!!

 

Thanks,

Deepak
