Work Description: stoty commented on pull request #2259:
URL: https://github.com/apache/hive/pull/2259#issuecomment-842975995
Here's what gets changed/removed from the distribution with the patch.
Apart from the obvious HBase libraries, there are some HBase dependencies.
The big one is Jersey 2.25. AFAICT, where Hive uses jersey, it includes the
older com.sun.jersey artifacts from Hadoop, so this shouldn't be a problem.
I have added some missing explicit dependencies where the Hive source used
undeclared dependencies for validation-api and commons-math3 .

> Hive currently packages HBase libraries into its lib directory.
> It also adds the HBase libraries separately to its classpath in the hive
> startup script.
> Having both mechanisms is redundant, and it also causes errors, as the
> standard HBase libraries packaged into Hive are unshaded, while the libraries
> added by _hbase mapredcp_
> are shaded, and the two are NOT compatible when custom coprocessors are used,
> and in some cases the classpaths during local execution and for MR/TEZ jobs
> are mutually incompatible.
> I propose removing all HBase libraries from the distribution, and pulling
> them via the hbase mapredcp mechanism.
> This also solves the old problem of including ancient HBase alpha versions
> Hive.
