Ignite YARN Kerberos - Delegation Ticket renewal

[Raghav <pu...@gmail.com>]

Ignite YARN not having a facility to renew HDFS_DELEGATION_TOKEN.

As Ignite-YARN is a long running application in YARN environment it should
have a mechanism to renew the delegation token. 

Version : 2.3.0
Module : Ignite-YARN
Class : ApplicationMaster

In Ignite-YARN, when the ApplicationMaster is started, it acquires
Delegation tokens and stores in a ByteBuffer[Class: ApplicationMaster,
Method: init()]. 
This ByteBuffer with token information is given to all the containers
received from ResourceManager [Class: ApplicationMaster, Method:
onContainersAllocated()]. 
Everything works fine till the life time of the delegation token. 
Once the delegation token expires, the ApplicationMaster is not able to
start Ignite inside containers it receive and below exception occurs 

WARNING: Error launching container

ApplicationMaster keeps on asking for more and more containers [Class:
ApplicationMaster, Method: run()] but not able to start Ignite inside any of
the containers due to the expired/missing delegation token. 
This repeats until all the resources in the cluster are allocated to
Ignition.

Kindly help in resolving the issue.

Thanks in Advance!!!
