TangLin commented on HDFS-17175:
--------------------------------
If two threads get for the same user like A, one id is 2 another is 3, 3 is
compelet, we should decrement, then B increament the id is 3, t2i map is A->3,
B->3, but i2t map is 3->B. When we setOnwer A, the user is always B.
> setOwner maybe set any user due to HDFS-16798
