John Doe updated HADOOP-19457:
------------------------------
Description: {{Map}} is accessed with {{get()}} and {{{}remove(){}}}.
Concurrently executing this twice can cause the removal to make {{get()}} to
return {{{}null{}}}, leading to {{{}NullPointerException{}}}. (was: The shared
resource can be assigned to null, while another member method later
dereferences it without a null check. This can cause a runtime failure when
fencing operations are triggered.)
