Hello All,
I am Shuubham Ojha a graduate researcher with the
University Of Melbourne. We have developed a block placement strategy which
optimises delay associated with reconstruction. As a result of this
optimisation problem, we get a placement matrix for blocks which tells us
which block has to be placed at which node. We have been able to implement
this strategy in Hadoop 2 by tweaking the file *placementmonitor.java* and
*blockmover.java* where *placementmonitor.java* monitors the placement
process and calls *blockmover.java* when the placement is not according the
strategy. However, I can't find any such file analogous to
*placementmonitor.java* in Hadoop 3 although I think that the closest file
which performs this function is *balancer.java* located in
hadoop-hdfs-project. Can anybody please provide me more information on this
front?
Warm Regards,
