Bikas Saha updated YARN-2052:
-----------------------------

    Description: Container ids are made unique by using the app identifier and 
appending a monotonically increasing sequence number to it. Since container 
creation is a high churn activity the RM does not store the sequence number per 
app. So after restart it does not know what the new sequence number should be 
for new allocations.

> ContainerId creation after work preserving restart is broken
