Hive inserting parquet files with different schema

I am trying to insert 2 parquet files to HDFS via hive.
the first one looks like

----------------

|col1|col2|col3|

----------------

 |1   |2   |3   |

----------------

when I select in HUE, I see this row correctly.
Then I insert the second file to the same table that looks like this:

---------------

 col3|col4|col5|

---------------

 31   |4   |5   |

---------------

The insert query works here but when I do a select query from all the rows, I get this output:

-------------------------

 col1|col2|col3|col4|col5|

-------------------------

 1   |2   |3   |null|null|

------------------------

NULL|NULL|31  |NULL|NULL|

------------------------

The second row should be null, null, 31,4,5
what am I doing wrong here?
