Lars George commented on HBASE-4243:
------------------------------------
Tested on MacOS Lion.
Patch works fine and actually triggers another bug

So the revert of the patch fell back to the older behavior of not going through
the if branch, which does not trigger the issue. Setting HADOOP_HOME externally
does trigger it as expected.
PS: Please upload the patch in SVN format (i.e. using --no-prefix with git for
example), just so that it conforms to standard
I am +1 applying the patch.
> HADOOP_HOME should be auto-detected

> Key: HBASE-4243
> URL: https://issues.apache.org/jira/browse/HBASE-4243
> Project: HBase
> Issue Type: Improvement
> Reporter: Roman Shaposhnik
> Assignee: Roman Shaposhnik
> Priority: Minor
> Attachments: HBASE-4243-2.patch.txt, HBASE-4243.patch.txt
>
>
> Now that HBASE-3465 has been integrated, perhaps we should try to auto-detect
> the HADOOP_HOME setting if it is not given explicitly. Something along the
> lines of:
> {noformat}
> # check for hadoop in the path
> 141 HADOOP_IN_PATH=`which hadoop 2>/dev/null`
> 142 if [ -f ${HADOOP_IN_PATH} ]; then
> 143 HADOOP_DIR=`dirname "$HADOOP_IN_PATH"`/..
> 144 fi
> 145 # HADOOP_HOME env variable overrides hadoop in the path
> 146 HADOOP_HOME=${HADOOP_HOME:-$HADOOP_DIR}
> 147 if [ "$HADOOP_HOME" == "" ]; then
> 148 echo "Cannot find hadoop installation: \$HADOOP_HOME must be set or
> hadoop must be in the path";
> 149 exit 4;
> 150 fi
> {noformat}
> Thoughts?
