Hi all,
I plan to use hive local in order to speed-up unit testing on (very) small
data sets. (Data is still on hdfs). I switch the local mode by setting the
following variables :
SET hive.exec.mode.local.auto=true;
SET mapred.local.dir=/user;
SET mapred.tmp.dir=file:///tmp;
(plus creating needed directories and permissions)
Simple GROUP BY, INNER and OUTER JOIN queries work just fine (with up to 3
jobs) with nice performance improvements.
Unfortunately I ran into a FileNotFoundException
:/tmp/vagrant/hive_2013-06-17_16-10-05_614_7672774118904458113/-mr-10000/1/emptyFile)on
some more complex query (4 jobs, distinct on top of several joins, see
below logs if needed).
Any idea about that error? What other option I am missing to have a fully
fonctional local mode?
Thanks in advance, Guillaume
