Hi Guys, Where I find Decommission document. I need to know how decommission will really works. Where I can find decommission logs.
How to understand decommission process: I am planning to remove one of my Datanode in my cluster. I have already Data available two other nodes. without data loss removing nodes. % How to actual data moving or transferring other nodes.? % When I start decommission the decommission initiated node send blocks to other machine % All the Blocks info will available in Namenode. NN will so replication steps Also I am facing issue very low speed Decommissioning will happening. for example I have data in 2TB it's take more than 50 hrs. It's quite unnormal. I believe I configured dfs.datanode.balance.bandwidthPerSec=1073741824 [1GB bytes per second] How to debug, Please guide guys. -Dhanasekaran Did I learn something today? If not, I wasted it.
