Ubuntu Linux, Institutional lab
Description
I want to use HDFS for storing the files in the institutional labs.
Here the point is to be noted that all the nodes in the labs are not of same type that is some nodes stay on for longer duration while some for small duration.
In addition to this all the labs are not same means that some lab has UPS facility and some has more nodes.
If I consider the lab as rack, then we should not choose the racks and node randomly in replica placement.
We should give more priority to those nodes that stay on for longer duration and to those lab which has lab facility and has more system.
