Description

I trying to 'CREATE EXTERNAL TABLE STORED AS KUDU' on the table with BINARY Kudu column data type and got an error: Kudu type 'binary' is not supported in Impala.
This limitation is not documented, checked:
https://impala.incubator.apache.org/docs/build/html/topics/impala_kudu.html
https://kudu.apache.org/docs/kudu_impala_integration.html#_known_issues_and_limitations

There are some thoughts that Kudu BINARY data type may be supported by Impala's STRING data type:
