添加节点/Hadoop [英] Adding Nodes / Hadoop

问题描述

Im trying to add some nodes in my existing cluster. Can I choose th amount of the hard drive space? Or can I only give the new nodes not more space than I gave to the existing nodes? (my nodes have each 12TB)

推荐答案

我可以选择多少硬盘空间?

Can I choose th amount of the hard drive space?

您不能选择空间"，但是可以选择用于数据节点的目录，总之，这些目录会添加到总可用空间中，是的.

You can't "choose space", but you can chose which directories are used for the data nodes, which in sum, add to the total availability space, yes.

并非所有的datanode都必须具有相同的大小

Not all datanodes need to be the same size
