Description

Class org.apache.hadoop.hive.ql.index.HiveIndex has invalid handler name 'org.apache.hadoop.hive.ql.AggregateIndexHandler'. The actual FQ class name is 'org.apache.hadoop.hive.ql.index.AggregateIndexHandler'

  public static enum IndexType {
    AGGREGATE_TABLE("aggregate", "org.apache.hadoop.hive.ql.AggregateIndexHandler"),
    COMPACT_SUMMARY_TABLE("compact", "org.apache.hadoop.hive.ql.index.compact.CompactIndexHandler"),
    BITMAP_TABLE("bitmap","org.apache.hadoop.hive.ql.index.bitmap.BitmapIndexHandler");

    private IndexType(String indexType, String className) {
      indexTypeName = indexType;
      this.handlerClsName = className;
    }

    private final String indexTypeName;
    private final String handlerClsName;

    public String getName() {
      return indexTypeName;
    }

    public String getHandlerClsName() {
      return handlerClsName;
    }
  }
  

Because all of the above statement like 'SHOW INDEXES ON MY_TABLE' doesn't work in case of configured 'org.apache.hadoop.hive.ql.index.AggregateIndexHandler' as index handler. In hive server log is observed java.lang.NullPointerException.
