Hi,
I'm trying to create indexes in Hive, and I've switched
to using CDH-4. The creation of the index is failing and
it's pretty obvious that the reducers are running out of
heap space. When I use the web interface for the
Hadoop reduce task list I can find this entry:
Error: Java heap space
try increasing ulimit on your hadoop cluster as well increase the memory
for map and reducer both by setting them up on hive
set mapred.job.map.memory.mb=6000;
set mapred.job.reduce.memory.mb=4000;
you can change the values based on the hadoop cluster you have setup
