Subject DFS Access Error
Date Tue, 19 May 2009 21:49:22 GMT
Dear Users,

When I tried to access the DFS, an error message apears:

Error: java.io.IOException: Unknown protocol to job tracker:
org.apache.hadoop.dfs.ClientProtocol
at
org.apache.hadoop.mapred.jobTracker.getProtocolVersion(JobTracker.java:163)

at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:481)
at org.apache.hadoop.ipc.Server$Handler.run(Server:java:890)

Hadoop version: 0.18.3

I'd appreciate your opinion!

George
