Before the modification the terminal output looked like this: ``` hadoop@ljq1:~/hadoop-3.1.3-work/sbin$ hdfs dfsadmin -safemode leave safemode: null Usage: hdfs dfsadmin [-safemode enter | leave | get | wait | forceExit] hadoop@ljq1:~/hadoop-3.1.3-work/sbin$ hdfs dfsadmin -safemode enter safemode: null Usage: hdfs dfsadmin [-safemode enter | leave | get | wait | forceExit] hadoop@ljq1:~/hadoop-3.1.3-work/sbin$ hdfs dfsadmin -safemode get safemode: null Usage: hdfs dfsadmin [-safemode enter | leave | get | wait | forceExit] hadoop@ljq1:~/hadoop-3.1.3-work/sbin$ hdfs dfsadmin -safemode forceExit safemode: null Usage: hdfs dfsadmin [-safemode enter | leave | get | wait | forceExit] ``` And after the modification provides a clear reminder that: ``` hadoop@ljq1:~/hadoop-3.1.3-work/sbin$ hdfs dfsadmin -safemode leave safemode: Invalid argument: dfs.client.mmap.cache.size must be greater than zero.
