-------------------------------------------------------------------
But when we write {{launch_container.sh}} also shouldn't we take care of all
{{nodemanger-whitelist}} could be taken from env which could help in
{{Docker}} ?.
If i add new property like {{HADOOP_MAPRED_HOME}} in {{nodemanger-whitelist}}
during launch {{HADOOP_MAPRED_HOME}} from docker env could be taken by default.
I do aggree that we do have another option to pass as env for each application
but if {{HADOOP_MAPRED_HOME}} is different in each image then could fail
randomly rt?
Plz do correct me if i am wrong.

But when we write to {{launch_container}} of also shouldn't we have to take
care,so that rather than Nodemanager default the system env could be taken
during launch container too. {{Docker}} case wouldnt this help?. If i add new
property like {{HADOOP_MAPRED_HOME}} in {{nodemanger-whitelist}} during launch
{{HADOOP_MAPRED_HOME}} from docker env we could take by default.
Plz do correct me if i am wrong.
