----------------------------------
> Remove HBase libraries from HBase distribution
> ----------------------------------------------
>
> Key: HIVE-25101
> URL: https://issues.apache.org/jira/browse/HIVE-25101
> Project: Hive
> Issue Type: Improvement
> Components: HBase Handler, Hive
> Affects Versions: 4.0.0
> Reporter: Istvan Toth
> Assignee: Istvan Toth
> Priority: Major
>
> 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.
