Rohini Palaniswamy commented on PIG-4253:
-----------------------------------------
bq. SequenceID generates a unique id for each records in the job. This unique
id is stable in task retry.
Patch is good. The name SequenceID seems to be kind of misleading as it makes
you think of a full sequence but it is only a sequence within the task. May be
you did not want to use UUID as that makes one expect a fixed length java like
UUID. Why not something like UniqueID which better explains the main purpose
and which is what the java doc for the class mentions anyways.
