> In HoodieLogFormatWriter, we use size() method of DataOutputStream to calculate the size of log block we write. However, this method only allows size no more than Integer.MAX_VALUE. When bytes we writen overflow, we will get a corrupted log block as the size of header is inconsistent with the one at footer
