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
