Zookeeper连接时KeeperException.java:102报错处理

报错内容

╭─root@esxi-kali /usr/share/zookeeper/bin  
╰─➤  ./zkCli.sh

此时使用的JAVA版本

╭─root@esxi-kali /usr/share/zookeeper/bin  
╰─➤  java -version                                                                                                                                         1 ↵
java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)

解决方法

修改zkEnv.sh文件中JAVA路径，使用openjdk

JAVA=/usr/lib/jvm/java-11-openjdk-amd64/bin/java

openjdk的JAVA版本

╭─root@esxi-kali /usr/share/zookeeper/bin  
╰─➤  /usr/lib/jvm/java-11-openjdk-amd64/bin/java -version
openjdk version "11.0.3" 2019-04-16
OpenJDK Runtime Environment (build 11.0.3+1-Debian-1)
OpenJDK 64-Bit Server VM (build 11.0.3+1-Debian-1, mixed mode, sharing)

修改后不再报错

╭─root@esxi-kali /usr/share/zookeeper/bin  
╰─➤  ./zkCli.sh -server 192.168.137.200 ls /                                                                                                             130 ↵
