-------------------------------------------

             Summary: 'DataNode maximum Java heap size' and 'Hadoop maximum Java heap size'
overrides for config groups didn't get persisted during installer
                 Key: AMBARI-4189
                 URL: https://issues.apache.org/jira/browse/AMBARI-4189

1. During hadoop installation 2 config groups were created for HDFS with overrides for properties
as in *hdfsInstaller.png*. 
2. After hadoop installation the config tab of Hdfs looks like *hdfsInMonitoring.png*

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}
