Harsh J commented on HDFS-4256:
-------------------------------
Suresh,
Thanks for commenting back!
bq. I also think protocol version upping can be done if we adding it in another
release like 1.2.0 right? Is there any issue with that?
bq. You see that in the questions asked on the mailing list where people are
still 0.20 release.
I am not strongly against this; but I do feel users wouldn't move to a higher
releases unless *we* urged them (we release it after all) and we haven't been
doing that in any good form.
This just feels like more backward work to me (moving features backwards,
'stead of just stability fixes and optimizations). But am not intending to
block it in any way - just wished to voice this cause users of HDFS stand to
benefit more with a full move ahead. Please go ahead :)
