Ajay Kumar commented on HDFS-12585:
-----------------------------------

[~vagarychen], thanks for review. Yes, {{propertyMap}}  is only initialized in 
{{loadDescriptions()}}. Since {{loadDescriptionFromXml}} default value is true 
{{loadDescriptions()}} will be called initially and there after we will use the 
initialized map. Main intention behind calling  {{loadDescriptionFromXml}}  is 
to load the description of properties from xml files which are not going to 
change frequently. So, we don't want to unmarshall xml files every time there 
is a call to servlet.
