[HIVE-3144] Custom Deserializers Should be Used for Thrift Table Objects

• Type: Bug

Description

Some tables have custom deserializers. When constructing the column set for these, the deserializer class should be used instead of just reading from the MetaStore. This is already happening when constructing the Table object in package org/apache/hadoop/hive/ql/metadata. However, Thrift API is returning incorrect results for these. We want to move this logic out of this Table object and lower into the stack to fix this.
