      Description

      In ChecksumFile.FSInputChecker, when a ChecksumException occurs, it tries to recover from the error by reading a different replica. However, the current code does not restore the Checksum object's old state. This causes a read not able to recover from ChecksumException although there are non-corrupted replicas available if the read follows a seek to a position which is not at the checksum chunk boundary .
