presto does not support redash when source is hive and external table exists

[derekennui]

When I run the query

SELECT table_schema, table_name, column_name
FROM hive.information_schema.columns
WHERE table_schema NOT IN ('pg_catalog', 'information_schema')

it reports error
failed: outputFormat should not be accessed from a null StorageFormat

I found the error in source code in com.facebook.presto.hive.metastore.StorageFormat,change the code

public String getOutputFormat()
{
if (outputFormat == null) {
return "null";
//throw new IllegalStateException("outputFormat should not be accessed from a null StorageFormat");
}
return outputFormat;
}

It works.

I'm not gonna query hive external table, but if I don't change the code above, I can't config the redash hive source.
