Tsz Wo (Nicholas), SZE commented on HADOOP-3883:
------------------------------------------------
One problem here is that namenode assigns two or more generation stamps to the
same block within a short period.
Namenode should remember the assign time of the previous generation stamp. If
the current generation stamp request is within a short period of the previous
one, Namenode should reject the request.
