I am newbie to Cloudera Hadoop . Working on Mapreduce program.
I would like to increase the datanode memory , nodemanager memory ,
Should I have to increase in the hadoop-env.sh and Yarn-site.xml in the below tags
I have been allocated around 128GB of RAM in my slave nodes.
So is there any base line to start with - more of a crap shot. My program is indeed a heavy computation.
if I want to increase the datanode memory should i have to the put the numbers inside HADOOP_DATANODE_OPTS ? or is there any other tags ? please help me on this.
any information is highly appreciable.
