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
Priority: Minor
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?
