Hii, I was playing around with hadoop. The command line hdfs tools seem to work fine.
When I ran a sample program to interact with hdfs in Java using eclipse. The commands ceased working at the command line properly. It appears as though Eclipse acquires some kind of lock which is held even after eclipse closes. Is there some way round this problem. I also noticed that when I start eclipse on running jps I fail to see the Datanode running. I formatted everything and reinstalled everything. Command line tools came back to normal but as soon as I rerun the program in eclipse the command line commands refuse to work properly. My dfs.replication is 1 My hadoop.tmp.dir is /home/apurv/fs -- -- thanks and regards, Apurv Verma
