Thanks very much. We use Ubuntu 8.0.4, and the kernel is 2.6.24-16-generic. When we run jps, it shows: 12405 startup.jar 5950 startup.jar 19216 SecondaryNameNode 25381 Jps 19053 NameNode 19289 JobTracker
When I pass "-o private" for fuse-dfs just as: fuse_dfs dfs://10.15.62.4:54310 /mnt/dfs -oprivate -d We see the debug message: port=54310,server=10.15.62.4 fuse-dfs didn't recognize /mnt/dfs,-2 fuse-dfs ignoring option -d FUSE library version: 2.8.1 nullpath_ok: 0 unique: 1, opcode: INIT (26), nodeid: 0, insize: 56 INIT: 7.9 flags=0x0000000b max_readahead=0x00020000 INIT: 7.12 flags=0x00000011 max_readahead=0x00020000 max_write=0x00020000 unique: 1, success, outsize: 40 unique: 2, opcode: GETATTR (3), nodeid: 1, insize: 56 getattr / unique: 3, opcode: GETATTR (3), nodeid: 1, insize: 56 getattr / # # An unexpected error has been detected by Java Runtime Environment: # # Internal Error (sharedRuntime.cpp:552), pid=25313, tid=1107450192 # Error: guarantee(cb != __null,"exception happened outside interpreter, nmethods and vtable stubs (1)") # # Java VM: Java HotSpot(TM) 64-Bit Server VM (10.0-b23 mixed mode linux-amd64) # An error report file with more information is saved as: # /tmp/hs_err_pid25313.log # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # Aborted When we list the /mnt/, the message is : ls: cannot access dfs: Transport endpoint is not connected Thanks.
