Out of Memory issue while executing simple Hive Query: java.lang.OutOfMemoryError: Java heap space

Hive Table:

Facing memory issues while querying!

Input file: JSON file

While researching on memory configuration, found some information here to calculate recommended memory configuration against available resources.

Our POC cluster size: 4 node cluster - 8 GB, 2 cores and 2 disks on each node

Please refer below information and let me know if memory needs to be extended or do TEZ memory configuration needs to be changed to overcome "out of memory" issue?

Calculated memory configuration uisng yarn-utils.py:

$ python yarn-utils.py -c 2 -m 8 -d 2 -k True

Using cores=2 memory=8GB disks=2 hbase=True

Profile: cores=2 memory=5120MB reserved=3GB usableMem=5GB disks=2

Num Container=4

Container Ram=1024MB

Used Ram=4GB

Unused Ram=3GB

yarn.scheduler.minimum-allocation-mb=1024

yarn.scheduler.maximum-allocation-mb=4096

yarn.nodemanager.resource.memory-mb=4096

mapreduce.map.memory.mb=1024

This issue is resolved by reducing container size (increase memory for paramers - yarn.scheduler.minimum-allocation-mb, and tez.task.resource.memory.mb)

Hi,

could you pleases tell me how to reducing container size. But, I executed query successfully but sometimes it got fails. please suggest it is very urgent issue going on.
