------------------------------
Summary: Hadoop Config shell script sets wrong environment if had
previous hadoop path
Key: AMBARI-6617
URL: https://issues.apache.org/jira/browse/AMBARI-6617
Project: Ambari
Issue Type: Bug
Components: client, controller
Affects Versions: 1.6.0
Environment: RHEL6
Reporter: Yixiao
I have previously installed Hadoop and had HADOOP_PREFIX, HADOOP_CONF_DIR in my
environment.
The hadoop-layout.sh and hadoop-config.sh was unable to set the hadoop
environment correctly. It will give error "class not found" error when trying
to start the HDFS service.
To reproduce this error: ("/tmp" is some path other than the Hadoop path)
$ export HADOOP_PREFIX=/tmp
$ export HADOOP_CONF_DIR=/tmp
$ source /usr/lib/hadoop/libexec/hadoop-config.sh
$ hadoop version
It will fail with class not found error.
Fix: unset any HADOOP related variable at the beginning of "hadoop-config.sh"
