It suggested that the problem is because the remote, given prompts to direct.
NOTE: If you turn off safe mode before adding resources, the NN will immediately return to safe mode. Use "hdfs dfsadmin -safemode leave" to turn safe mode off.
Has told us that the use of
hdfs dfsadmin -safemode leave
The security model is closed, but after closing the safe mode executed again found the same statement still get the same result, access to information, because of lack of space caused memory.
# Use df -hl view space usage df -hl # Use du -sh / * to see which files are taking up a large space you -sh / * # After the release of the corresponding memory space, the problem is solved.
