> 1. During hadoop installation 2 config groups were created for HDFS with overrides for properties. 
> 2. After hadoop installation go to the config tab of Hdfs.
> Checked that 2 other properties 'DataNode directories' and 'Reserved space for HDFS' were persisted correctly for both config groups. 
> But the 'DataNode maximum Java heap size' and 'Hadoop maximum Java heap size' have the same default values in /etc/hadoop/conf/hadoop-env.sh: 
> {noformat}
> export HADOOP_HEAPSIZE="1024"
> ...
> HADOOP_DATANODE_OPTS="-Xmx1024m -Dhadoop.security.logger=ERROR,DRFAS ${HADOOP_DATANODE_OPTS}"
> {noformat}
