HDFS如何管理块大小? [英] How does HDFS manage block size?

问题描述

我的文件大小为65MB，默认的hdfs块大小为64MB，那么将为我的文件分配多少个64MB块?

My file size is 65MB and default hdfs block size(64MB), then how many 64MB blocks will be allotted to my file?

是1-64MB块，1-1MB块还是2-64MB块?如果它是2-64MB的块，它将浪费掉63MB的其余部分，还是会分配给其他文件?

Is it like 1-64MB block, 1-1MB block or 2-64MB blocks? If it is 2-64MB blocks is it going to be wasted rest of the 63MB or will it be allocated to other file?

推荐答案

块大小64MB表示块的上限大小.这并不意味着小于64MB的文件块将消耗64MB.存储1MB的块不会消耗64MB.

Block size 64MB means an upper bound size for a block. It doesn't mean that file blocks less than 64MB will consume 64MB. It will not consume 64MB to store a chunk of 1MB.

如果文件为 160兆字节，
