Handle Hive arrays

Version of DBeaver: 4.0.1 on Ubuntu 16.04

DBeaver seems not to be able to handle hive’s arrays.

I have multiple columns such as:

• gain ARRAY<FLOAT>
• units ARRAY<STRING>
• baseline ARRAY<INT>

and the displayed value in DBeaver when browsing tables is “NULL”. Plus I have the following warning:

Unsupported array type: java.lang.String
org.jkiss.dbeaver.model.exec.DBCException: Unsupported array type: java.lang.String

Do you think it could be possible to handle arrays?

Thanks!

Hive driver doesn’t support JDBC array but returns arrays as strings. I did some basic string->array translation. This should work ok in read-only mode.

You can check it in new EA version.
