Jonathan Eagles updated TEZ-1526:
---------------------------------
Description: Using the LoadingCache with default builder settings. 100,000
TezTaskIDs are created in 10 seconds on my setup. With a LoadingCache
initialCapacity of 10,000 they are created in 300 ms. With no LoadingCache,
they are created in 10 ms. A test case in attached to illustrate the condition
I would like to be sped up.
