Ticket标题：The number of bytes of the last committed block should be calculated into the file length。
HDFS里，一个在写入的文件可能包含多个commited状态的块。
但是计算文件大小的时候，最后一个commited block并没有被计算进去，但是却包含了其他的commited blocks。
如下代码：
/*** Compute file size of the current file.* * @param includesLastUcBlock* If the last block is under construction, should it be included?* @param usePreferredBlockSize4LastUcBlock* If the last block is under construction, should we use actual* block size or preferred block size?* Note that usePreferredBlockSize4LastUcBlock is ignored* if includesLastUcBlock == false.* @return file size*/<这篇关于【HDFS】关于HDFS-17497：在commit block时更新quota的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
