Description: ======================
        Pandas HBase IO Helper
        ======================
        
        Persist pandas DataFrame objects to HBase and read them back later.
        
        Known Issues:
        - Works only with DataFrames that have integer indices.
        - DataFrames to be persisted should not have ':' in column names
        
        Writing DataFrame to HBase
        --------------------------
        
        
        Establish hbase connection using happybase and write the dataframe.
        
        .. code-block:: python
            import happybase
            import numpy as np
            import pandas as pd
            import pdhbase as pdh
            connection = None
            try:
                connection = happybase.Connection('127.0.0.1')
                connection.open()
                df = pd.DataFrame(np.random.randn(10, 5), columns=['a', 'b', 'c', 'd', 'e'])
                df['f'] = 'hello world'
                pdh.to_hbase(df, connection, 'sample_table', 'df_key', cf='cf')
            finally:
                if connection:
                    connection.close()
        
        
        Reading DataFrame from HBase
        ----------------------------
        
        
        Establish hbase connection using happybase and read the dataframe.
        
        .. code-block:: python
            import happybase
            import numpy as np
            import pandas as pd
            import pdhbase as pdh
            connection = None
            try:
                connection = happybase.Connection('127.0.0.1')
                connection.open()
                df = read_hbase(connection, 'sample_table', 'df_key', cf='cf')
                print df
            finally:
                if connection:
                    connection.close()
