[jira] [Created] (ARROW-5986) [Java] Code cleanup for dictionary encoding

Ji Liu created ARROW-5986:
-----------------------------

             Summary: [Java] Code cleanup for dictionary encoding
                 Key: ARROW-5986
                 URL: https://issues.apache.org/jira/browse/ARROW-5986
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Java
            Reporter: Ji Liu
            Assignee: Ji Liu


In last few weeks, we did some refactor in dictionary encoding.

Since the new designed hash table for {{DictionaryEncoder}} and {{hashCode}} & {{equals}} API in {{ValueVector}} already checked in, some classed are no use anymore like {{DictionaryEncodingHashTable}}, {{BaseBinaryVector}} and related benchmarks & UT.

Fortunately, these changes are not made into version 0.14, which makes possible to remove them.
