WiP: IMPALA-10798 : Prototype for JSON reader
This prototype allows user to create a table stored as jsonfile and
query it.
Steps to test:
- create a json table with schema specified using eligible datatypes
(int8/16/32/64/float/double/string/varchar/char)
- add your json file (with eligble datatypes and same column names as
schema specified in the create command) to hdfs location
- add this 'location' to your table
- run a select statement
Fix:
- arrow library is included wherever required
- json format is added to scan node base class.
- json scanner files are added, that implement methods to read the
json file from the specified file location
