Dear all, I want to know if their is any class or any way to access the file list and meta data from a remote HDFS namenode. for example, there are two hadoop instances, which mean two namenodes (nn1 and nn2) If I was super user in both two hadoop instances, and now I am in nn1, want to get nn2's file list and meta data Is there any way to get that?
Now I could just try the most traditional way, which is si...@nn1:~$ ssh nn2 "/hadoop/bin/hadoop fs -lsr " and then parse the result to get each file's meta data Is there any class or api I could use with? My dream way is to make my own jar in nn1, through bin/hadoop jar remote.jar remote I can get certain directory inform of remote hdfs thanks a lot Best Regards, Simon
