原因是环境变量少配置了一个东西 ，再环境变量中配置

export JAVA_HOME=/home/jackray/jdk1.8.0_241
    export MAVEN_HOME=/home/jackray/apache-maven-3.6.2
    export HADOOP_HOME=/home/jackray/hadoop-3.2.1
    export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
    export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"
    export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/lib/tools.jar:$MAVEN_HOME/bin:$HADOOP_HOME/bin

配置这两项

export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
    export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"

然后执行

hdfs --daemon start zkfc

不再报错  
查看java进程

2385 QuorumPeerMain
    5506 Jps
    5325 DFSZKFailoverController
    2591 JournalNode

DFSZKFailoverController已经启动 解决问题
