[jira] Created: (HADOOP-4042) bin/hadoop should check `which java`
to find java
bin/hadoop should check `which java` to find java
-------------------------------------------------
Key: HADOOP-4042
URL: https://issues.apache.org/jira/browse/HADOOP-4042
Project: Hadoop Core
Issue Type: Bug
Components: scripts
Affects Versions: 0.18.0
Reporter: Michael Bieniosek
Priority: Minor
Currently, the bin/hadoop script tries to find java in JAVA_HOME/bin/java. If the bin/hadoop script isn't there, it errors out.
Instead, I think it should check `which java 2>/dev/null` to see if there is a java on the user's PATH. If a java is on the user's path, the script should just set JAVA=java.

Doug Cutting commented on HADOOP-4042:
--------------------------------------
This sounds reasonable and is what e.g., Ant's scripts do, so there's precedent.

Michael Bieniosek updated HADOOP-4042:
--------------------------------------
Description:
Currently, the bin/hadoop script tries to find java in JAVA_HOME/bin/java. If JAVA_HOME is not set, it errors out.
Instead, I think it should check `which java 2>/dev/null` to see if there is a java on the user's PATH. If a java is on the user's path, the script should just set JAVA=java.
