Eli Collins updated HADOOP-6605:
--------------------------------
Description: The commands that source hadoop-config.sh currently bail
with an error if JAVA_HOME is not set. Let's detect JAVA_HOME (from a list of
locations on various OS types) if JAVA_HOME is not already set by hadoop-env.sh
or the environment. This way users don't have to manually configure it. (was:
JAVA_HOME can be set in hadoop-env.sh and hadoop-config.sh should respect this.
hadoop-config will source hadoop-env after it determines a config directory. If
JAVA_HOME still isn't set, it will try to guess one from a list of Linux usual
locations. If one still isn't set it will quit with a verbose error message.)
Priority: Minor (was: Major)
Affects Version/s: (was: 0.20.2)
Fix Version/s: 0.22.0
Assignee: Eli Collins (was: Chad Metcalf)
Summary: Add JAVA_HOME detection to hadoop-config (was: Improve
JAVA_HOME detection and handling in hadoop-config)
