Hello, I tried using DataNodeCluster to simulate a set of 3000 datanodes. The namenode is already running.
When I gave the below command : $ java DataNodeCluster -n 3000 -simulated -inject 1 1 -d someDirectory I am getting the following error: Starting 3000 Simulated Data Nodes that will connect to Name Node at gs301850.inktomisearch.com:50830 Starting DataNode 0 with dfs.data.dir: someDirectory/dfs/data/data1,someDirectory/dfs/data/data2 08/12/22 11:42:33 INFO datanode.DataNode: Registered FSDatasetStatusMBean 08/12/22 11:42:33 INFO datanode.DataNode: Opened info server at 60195 08/12/22 11:42:33 INFO datanode.DataNode: Balancing bandwith is 1048576 bytes/s 08/12/22 11:42:33 INFO datanode.DataNode: Periodic Block Verification is disabled because verifcation is supported only with FSDataset. 08/12/22 11:42:33 INFO http.HttpServer: Version Jetty/5.1.4 08/12/22 11:42:33 INFO util.Container: Started HttpContext[/static,/static] 08/12/22 11:42:34 INFO util.Credential: Checking Resource aliases 08/12/22 11:42:34 INFO util.Container: Started org.mortbay.jetty.servlet.webapplicationhand...@1f03691 08/12/22 11:42:34 INFO http.SocketListener: Started SocketListener on 127.0.0.1:60196 08/12/22 11:42:34 INFO datanode.DataNode: Waiting for threadgroup to exit, active threads is 0 Error creating data node:java.io.IOException: Problem starting http server The system just hangs after the above message.
