When number of records written is zero, averageBytesPerRecord results in a huge size (division by zero and ceiled to Long.MAX_VALUE) causing OOM. This commit fixes this issue by reverse traversing the commits until a more reasonable average record size can be computed and if that is not possible returns the default configured record size.
