Vinod KC updated SPARK-54552:
-----------------------------
Description:
The getString() method in _SparkConnectResultSet_ does not properly handle
BINARY data types. When calling getString() on a column with `BINARY` type, the
method uses String.valueOf() on the raw byte array, which produces an incorrect
string representation (e.g., "[B@<hashcode>") instead of converting the bytes
to a proper UTF-8 string.
eg:
{code:java}
SELECT binary('xDeAdBeEf')
spark-sql: `\xDeAdBeEf`
beeline with STS: `\xDeAdBeEf`
beeline with Connect Server: `[B@4d518c66`{code}
