> Disable hdfsEncryptionShims cache during query-based compaction

> Project: Hive
> Issue Type: Bug
> Reporter: Karen Coppage

> Hive keeps a cache of encryption shims in SessionState (Map<URI,
> HadoopShims.HdfsEncryptionShim> hdfsEncryptionShims). Each encryption shim in
> the cache stores a FileSystem object.
> After compaction where the session user is not the same user as the owner of
> the partition/table directory, we close all FileSystem objects associated
> with the user running the compaction, possibly closing an FS stored in the
> encryption shim cache. The next time query-based compaction is run on a
> table/partition owned by the same user, compaction will fail in MoveTask[1]
> since the FileSystem stored in the cache was closed.
> This change disables the cache during query-based compaction (optionally;
> default: disabled).
