-----------------------------------------------------------------
BTW, yesterday I meant to post this comment, and noticed I had not:
bq. It's not obvious from looking at StringUtils#getUidBytes why it must return
an array of size 16 exactly; using a class would help.
Isn't it well know that UUID is 16 octets? Not sure a class would add any more
clarity. However, we can add a comment where we check for the clientID size to
clarify this. This will be done in the patch with HADOOP-9770.
