> Key: HDFS-16653
> URL: https://issues.apache.org/jira/browse/HDFS-16653
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: dfsadmin
> Affects Versions: 3.1.3
> Environment: Linux version 4.15.0-142-generic
> (buildd@lgw01-amd64-039) (gcc version 5.4.0 20160609 (Ubuntu
> 5.4.0-6ubuntu1~16.04.12))
> Reporter: Jingxuan Fu

> {code:java}
> <property>
> <name>dfs.client.mmap.cache.size</name>
> <value>256</value>
> <description>
> When zero-copy reads are used, the DFSClient keeps a cache of recently
> used
> memory mapped regions. This parameter controls the maximum number of
> entries that we will keep in that cache.
> The larger this number is, the more file descriptors we will potentially
> use for memory-mapped files. mmaped files also use virtual address space.
> You may need to increase your ulimit virtual address space limits before
> increasing the client mmap cache size.
>
> Note that you can still do zero-copy reads when this size is set to 0.
> </description>
> </property>
> {code}
> When the configuration item “dfs.client.mmap.cache.size” is set to a negative
> number, it will cause /hadoop/bin hdfs dfsadmin -safemode provides all the
> operation options including enter, leave, get, wait and forceExit are
> invalid, the terminal returns security mode is null and no exceptions are
> thrown.
> {code:java}
> hadoop@ljq1:~/hadoop-3.1.3-work/etc/hadoop$ hdfs dfsadmin -safemode leave
> safemode: null
> Usage: hdfs dfsadmin [-safemode enter | leave | get | wait | forceExit] {code}
> In summary, I think we need to improve the check mechanism related to this
> configuration item, and give a clear indication when the configuration is
> abnormal in order to solve the problem in time and reduce the impact on the
> safe mode related operations.
