                    I'm currently experimenting with using the new
                    HBaseKeyFactory interface (implemented in <a
                      moz-do-not-send="true"
                      href="https://issues.apache.org/jira/browse/HIVE-6411"
                      target="_blank">https://issues.apache.org/jira/browse/HIVE-6411</a>)
                    to do some custom serialization and predicate
                    pushdown on our HBase schema. Ideally, I'd like to
                    be able to use the information from the
                    hbase.columns.mapping property on the table, and
                    indeed, AbstractHBaseKeyFactory seems to support
                    this use case, exposing a protected
                    ColumnMappings.ColumnMapping keyMapping member.
                    However, ColumnMappings.ColumnMapping exposes no
                    public members (everything is package private
                    org.apache.hadoop.hive.hbase), meaning that I can't
                    read any data from the ColumnMapping in my custom
                    HBaseKeyFactory. <br>
                    <br>
                    Is this behavior intentional? Obviously I could work
                    around this by declaring my factory in the same
                    package, but it seems like the user experience would
                    be better if there were public accessors for the
                    fields in ColumnMappings.ColumnMapping. Is there
                    another way to do this that I'm missing? If this
                    isn't intentional, I'll raise a JIRA issue and
                    submit a (small) patch.<br>
