This is a good question. once data is load into Spark, string type must be a UTF-8 encoded binary. If it's not, then data loading (table reading) has a bug. It's a little weird to hear that: hive table reading is fine, but the writing after reading is problematic because string is not UTF8 encoded. Seems like the table reading is wrong at the first place (produce non-utf8-encoded string).
