Greetings, I'm trying to setup HDFS on a single-node cluster. I've tried several tutorials, but all of them lead to the same problem. After the setup I can check that everything is working using:
jps ... 17421 NameNode 17519 DataNode 17611 SecondaryNameNode 17685 JobTracker 17778 TaskTracker 18425 Jps ... AND sudo netstat -plten | grep java ... tcp 0 0 127.0.0.1:54310 0.0.0.0:* LISTEN 1062 346907 17421/java (namenode) tcp 0 0 127.0.0.1:54311 0.0.0.0:* LISTEN 1062 347480 17685/java (job tracker) ... The log files, too, don't report any error. The problem I get is that running /bin/hadoop dfs -ls (or copyFromLocal, etc.) the command is not executed, it just remains here and doesn't complete / exit. No errors are reported in the log files. Have someone faced this problem or knows what can be it solution? Thanks in advance, best regards
