Wojciech Langiewicz commented on HADOOP-4042: --------------------------------------------- I don't know how this would affect performance issues, but on my system 'which java' shows /usr/bin/java, which is a symlink to /etc/alternatives/java, which is a symlink to /usr/lib/jvm/java-6-openjdk/jre/bin/java. and $JAVA_HOME points directly to /usr/lib/jvm/java-6-openjdk > bin/hadoop should check `which java` to find java > ------------------------------------------------- > > Key: HADOOP-4042 > URL: https://issues.apache.org/jira/browse/HADOOP-4042 > Project: Hadoop Common > 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 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
