"I see that the hive community intends to make hive SQL compliant and is on
that path." . I was not under the general impression that we are on that
Someone once told me that supporting full SQL will result in roughly 4
times the parser and planner code. For me that is not a huge win.
Also some SQL operations can not be executed efficiently in map-reduce and
should IMHO not be added to the language. IE if doing the operation means
all data must be shuffled to a single reducer its not something hive should
I do not think hive should be mis-representing itself. Simply put, hive is
NOT SQL complaint we should NOT call the language SQL.
Doing so would only only lead to confusion for people new to the project.
Imagine you are new to hive:
You read "SQL"in the documentation.
You run an "SQL" standard create table query, it fails.
You struggle creating the table, finally you get it created, and then run
an SQL complaint correlated sub query, and that fails.
You say to you self "What a fricken piece of crud this hive is! they claim
it's SQL but it's not. What else are they lying to me about?"
