Review comment:
This method is called only
(here)[https://github.com/apache/incubator-nemo/pull/314/files] and It is
called at separated thread. I'll add a comment about this context.
But anyway It is too inefficient that creating an additional thread for
every task. However If I want to separate this, I have to store the created
taskExecutors in Executor, And It is implemented (not merged
PR)[https://github.com/apache/incubator-nemo/pull/314/files]. Is It okay to
implement same Map in this PR?

Review comment:
As I know, every getter is used when metrics are stored in json file.
If it is not exist, createdTaskId does not stored in json file
