Sahil Takiar commented on HIVE-15982:
-------------------------------------
[~cartershanklin] could we double check the SQL standard for this? Is the
statement "If wbo < wbb1, return 1" correct? It seems both Oracle and Postgres
return 0 instead of 1
> Support the width_bucket function

> Support the width_bucket(wbo, wbb1, wbb2, wbc) which returns an integer
> between 0 and wbc+1 by mapping wbo into the ith equally sized bucket made by
> dividing wbb1 and wbb2 into equally sized regions. If wbo < wbb1, return 1,
> if wbo > wbb2 return wbc+1. Reference: SQL standard section 4.4.
