> {noformat}
> create table test (f1 int, f2 int);
> insert into table test values (10,10);
> {noformat}
> This ends up creating 6 containers (HiveInput creates 6 splits) in hive1
> queue in cn041 cluster. Accidentally one could use couple of JDBC programs
> to use up all available slots with simple inserts.
> Appears that "mapreduce.input.fileinputformat.split.minsize" is set to 1.
> Setting it to a higher value
> "mapreduce.input.fileinputformat.split.minsize=1000000" fixes the problem and
> launches 1 container.
