-Re: Converting array<tinyint> in Flume avro default output to string in Hive
Not really sure there is a direct way to concat anything other than strings
in hive unless typecasting them to string.
So you may want to keep the datatype of array elements to strings and try.
else you may want to build your own udf to do it which looks more elegant
way rather than just typecasting it.
