Review request for Ambari and Andrew Onischuk.
Bugs: AMBARI-11837
https://issues.apache.org/jira/browse/AMBARI-11837
Repository: ambari
Description
-------
{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.
