问题是
hduser@saket-K53SM:/usr/local/hadoop$ jps
The program 'jps' can be found in the following packages:
* openjdk-6-jdk
* openjdk-7-jdk
Try: sudo apt-get install <selected package>
我的配置是
hduser@saket-K53SM:/usr/local/hadoop$ java -version
java version "1.6.0_33"
Java(TM) SE Runtime Environment (build 1.6.0_33-b04)
Java HotSpot(TM) 64-Bit Server VM (build 20.8-b03, mixed mode)
设置 conf/hadoop-env.sh
hduser@saket-K53SM:/usr/local/hadoop$ cat conf/hadoop-env.sh | grep JAVA_HOME
# The only required environment variable is JAVA_HOME. All others are
# set JAVA_HOME in this file, so that it is correctly defined on
export JAVA_HOME=/usr/lib/jvm/jdk1.6.0_33/
我知道有一个与此类似的问题(http://stackoverflow.com/questions/7843422/hadoop-jps-can-not-find-java-installed)。但是我在这里安装了 Sun jdk。所以任何帮助将不胜感激..
