Re: descentralized write operation in HDFS

Not that I know of, the block allocations are done by the NameNode for several reasons/edge cases, and that is why the write path is as it is today. What problem are you trying to solve though, that led you to ask this? If we have more info about the problem to solve, we can provide better answers

descentralized write operation in HDFS

Hi, It is possible to write to a HDFS datanode w/o relying on Namenode, i.e. to find the location of Datanodes from somewhere else ? Thanks, Robert
