问题描述
限时送ChatGPT账号..
我的配置是
hduser@worker1:/usr/local/hadoop/conf$ jps
The program 'jps' can be found in the following packages:
* openjdk-6-jdk
* openjdk-7-jdk
Ask your administrator to install one of them
我已经安装了java
hduser@worker1:/usr/local/hadoop/conf$ java -version
java version "1.6.0_23"
OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b23~pre10-0ubuntu5)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)
hduser@worker1:/usr/local/hadoop/conf$ echo $JAVA_HOME
/usr/lib/jvm/java-1.6.0-openjdk
并且也在conf/hadoop-env.sh
hduser@worker1:/usr/local/hadoop/conf$ cat 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/java-1.6.0-openjdk
如何使 JPS 工作?
How can I make JPS work?
推荐答案
好像open-jdk里面没有jps.对于hadoop，安装sun-jvm会是更好的选择.
It seems like open-jdk does not have jps in it. For hadoop, installing sun-jvm would be a better choice.
