how to increase spark's worker memory from CM

avatar
Expert Contributor

i am working on a cluster of 1 master and 2 workers , when i open spark master UI 

Memory: 128.0 MB Total

each worker memory 64.0 MB (0.0 B Used) 

while each worker has 4 GB memory in total and 2.5 GB free memory   , so i want to increase the worker memory instead of 64 to make it 1 GB , i tried to find spark-defaults.conf in /etc/spark/conf.cloudera.spark   but it doesn't exist , i am running cloudera manager 5.0.2 , i guess there might be a configuration that can be done to increase the memory from cloudera manger => spark service , but i can't find it 

 

Thanks in advance
