> I use the linux shell to put the file into the hdfs throuth the hdfs nfs gateway. I found
that if the file which size is smaller than one block(128M), it will still takes one block(128M)
of hdfs storage by this way. But after a few minitues the excess storage will be released.
> e.g:If I put the file(60M) into the hdfs throuth the hdfs nfs gateway, it will takes
one block(128M) at first. After a few minitues the excess storage(68M) will
> be released. The file only use 60M hdfs storage at last.
> Why is will be this?
