Hello, I'm having some problems setting up my datanodes, I have a 4 node cluster (all of them are datanodes), if I run
sudo -u hdfs hadoop dfsadmin -report Configured Capacity: 112231907328 (104.52 GB) Present Capacity: 54121451520 (50.4 GB) DFS Remaining: 54120173568 (50.4 GB) DFS Used: 1277952 (1.22 MB) DFS Used%: 0% Under replicated blocks: 1 Blocks with corrupt replicas: 0 Missing blocks: 0 ------------------------------------------------- Datanodes available: 1 (1 total, 0 dead) Name: <my-ip>:50010 Decommission Status : Normal Configured Capacity: 112231907328 (104.52 GB) DFS Used: 1277952 (1.22 MB) Non DFS Used: 58110455808 (54.12 GB) DFS Remaining: 54120173568(50.4 GB) DFS Used%: 0% DFS Remaining%: 48.22% Last contact: Thu Apr 28 18:39:28 CEST 2011 The report only show 1 datanode! Checking the logs of the slaves I found this: 2011-04-28 18:26:09,587 INFO org.apache.hadoop.ipc.Client: Retrying connect to server: slave/<ip>:54310. Already tried 9 time(s). 2011-04-28 18:26:09,588 INFO org.apache.hadoop.ipc.RPC: Server at slave/<ip>:54310 not available yet, Zzzzz... I don't know what to do....Should I configure passwordless ssh between the servers? Thanks
