> On YARN-2052, we changed containerId format: upper 10 bits are for epoch,
> lower 22 bits are for sequence number of Ids. This is for preserving
> semantics of {{ContainerId#getId()}}, {{ContainerId#toString()}},
> {{ContainerId#compareTo()}}, {{ContainerId#equals}}, and
> {{ConverterUtils#toContainerId}}. One concern is epoch can overflow after RM
> restarts 1024 times.
> To avoid the problem, its better to make containerId long. We need to define
> the new format of container Id with preserving backward compatibility on this
> JIRA.
