在安装hadoop时，执行JPS出现下面错误

 

[slave16][email protected]:/tmp/hsperfdata_hdfs# jps

Error occurred during initialization of VM

java.lang.Error: Properties init: Could not determine current working directory.

        at java.lang.System.initProperties(Native Method)

        at java.lang.System.initializeSystemClass(System.java:1119)

 

从错误知道JVM有问题，可以执行java -version命令：

[slave16][email protected]:/tmp/hsperfdata_hdfs#  java -version

Error occurred during initialization of VM

java.lang.Error: Properties init: Could not determine current working directory.

        at java.lang.System.initProperties(Native Method)

        at java.lang.System.initializeSystemClass(System.java:1119)

 

说明jdk路径没生效，执行source ~/.bashrc 命令，再次执行则能正常列出各程序

            

[slave16]root@192.168.11.10:~# source .bashrc

[slave16]root@192.168.11.10:~# java -version
