Subject Does Hive SQL support reading data without locking?
Date Tue, 02 Jan 2018 03:59:43 GMT
Hi, All,

We are using Hive to persist our data and we run cron jobs to import new 
data into Hive daily.

At the same time, our users may query data from Hive at the same time by 
using a third party software like Tableau

We found an issue that importing job will fail while the table is queried 
by user because of failing to get an exclusive lock 

Does Hive SQL support reading data without locking (read lock) just like 
'with (nolock)' provided by SQL server?

Thanks 

Boying
