我在hadoop安装了 Cloudera CDH 4.3 的机器上运行命令，遇到了这个错误：
/workplace/cloudera/parcels/CDH-4.3.1-1.cdh4.3.1.p0.110/bin/../lib/hadoop/bin/hadoop: line 139: /opt/java/latest/bin/java: No such file or directory
/workplace/cloudera/parcels/CDH-4.3.1-1.cdh4.3.1.p0.110/bin/../lib/hadoop/bin/hadoop: line 139: exec: /opt/java/latest/bin/java: cannot execute: No such file or directory
然后我检查了那台机器上的java，发现它已经安装但在不同的位置：
whereis java
java: /usr/bin/java /etc/java /usr/lib/java /usr/share/java /usr/share/man/man1/java.1.gz
我怎样才能让 CDH4 从中获取 java /usr/bin/java？
