Sorry, I found the previous one is full of typo and hard to understand. I will clarify my question:
If I have got a inputstream in a datanode (and this stream contains exactly 64MB's data which I want to store it as a data block of the HDFS in that datanode. More specifically, I want to use this block to replace another exsiting block of one file that already stored in the HDFS), can anyone tell me which is the easiest way to do this?
