Allen Wittenauer commented on HADOOP-12857:
-------------------------------------------
bq. Would it make sense to leave these alone as special cases for now and defer
improving them to a separate patch? I think the primary benefit of this
proposal is improved manageability of the truly optional components.
Two things lead me to the answer no:
a) More than half of the bits in hadoop-tools are being called by a script. (I
know! it's way more than I expected!) The optional components are in the
minority.
b) We'll definitely end up with duplicate jars in the classpath for those bits.
(The classpath de-duper doesn't expand the asterisks.)
But really, it's not that much extra just do it in one pass. I'll likely have
a patch in the next day or so. (ofc, being unemployed helps haha)
