删除Hadoop文件系统（HDFS）中的文件

Question

I left a sqoop job running and it completely filled the hdfs(100%). Now i cannot delete the files in Hdfs. It is giving me an execption

    # hdfs dfs -rm -skipTrash /TEST_FILE 
    rmr: Cannot delete /TEST_FILE. Name node is in safe mode.

I used hdfs dfsadmin -safemode to leave out of safe mode.

    [hdfs@sandbox /]$ hdfs dfsadmin -safemode leave
    Safe mode is OFF 

But when i try again deleting the file using hdfs dfs -rm -skipTrash /TEST_FILE iam getting error message that NameNode is in safemode

I am unable to leave safemode and delete the file.

can anyone help me how to get out of safemode and delete the file?

Answer 1

Namenode cannot be brought out of safe mode with the command "hdfs dfsadmin -safemode leave" unless you are really cleaning up something . if you dont do anything and use the command , the name node will go back to safe mode . Since you are using the single node cluster , you can try cleaning up your log directories /var/log/ ... and bring the name node out of safe mode and delete the hdfs directory left by sqoop
