Decommission datanode
Hi, I don't have much data, but it took around 40 minutes to decommission. How long will it take to decommission a datanode? Is there any way to optimize the process? Thanks.
Decommission DataNode
In CDH3u5, when the DataNode is Decommissioned, the DataNode progress will be shutdown by NameNode. But In CDH4.3.1, when the DataNode is Decommissioned, the DataNode progress will be not shutdown by NameNode. When the datanode is Decommissioned, why the datanode is not automatically shutdown
