Saved avro file's(raw data files, collect by flume) schema contains map type.
I want to create table using it.
I know Impala not support map type.
So, I removed the map type from the avro schema.( map type column remove )
Avro files still has map type data.
And, I create Hive and Impala table.
And, add partitions.
Hive table have rows.
But Impala no have rows.
Impala table query raise exception(complex type).
How do I create an impala table in an avro file(raw data) that already has a map type?
