The StreamBaseRecordReader is unable to log record data that's not UTF-8

Streaming code at times can work on data that's not UTF-8, for instance image/audio data. The StreamBaseRecordReader tries to log some status info, which contains part of the record, using the LOG.info() call. This call throws this exception :
