Anu Engineer commented on HDFS-12537:
-------------------------------------
[~ljain] Looks very good to me. Thanks for getting this done. Two very minor
comments.
1. Can we make the OptimizeWrite the default option so while testing I don't
have to specify that. So the option will be reverse like "DoNotUseFastWrite" or
something. I will tell you when not to use that fast option.
2. Can we please add the Date time of the execution itself. So example, if I
look at a json file later, I would like to know date and time when the
execution happened.
With those changes, the patch looks good to me.

> of overhead. An option should be provided to use a single key value.
