I am running a hive query something like this(ignore the syntax if it is incorrect) in hive action in oozie
Insert overwrite table partition(col=x)select * from table
And I see the number of reducers are set to 1 in all the reducer stages and the query is taking too much time, but the same query when I ran through beeline using shell action in oozie, I can see so many reducers and the query is running fast.
can anyone please tell me what could be the reason behind this.
