Examples of org.apache.hadoop.hbase.index.IndexedHTableDescriptor

org.apache.hadoop.hbase.index.IndexedHTableDescriptor
IndexedHTabledDescriptor is extension of HTableDescriptor. This contains indices to specify index name and column details. There can be one or more indices on one table. For each of the index on the table and IndexSpecification is to be created and added to the indices.
