---------------------------------------

             Summary: Allow disabling hadoop classpath and native library lookup
                 Key: HBASE-13120
                 URL: https://issues.apache.org/jira/browse/HBASE-13120
             Project: HBase
          Issue Type: Improvement
          Components: hbase
    Affects Versions: 0.98.0
            Reporter: Siddharth Wagle


- Current bin/hbase script sets the java.library.path to include hadoop native libs based on what version of hadoop is installed on the box.
{code}
HADOOP_IN_PATH=$(PATH="${HADOOP_HOME:-${HADOOP_PREFIX}}/bin:$PATH" which hadoop 2>/dev/null)
{code}

- This effectively means that a self-contained HBase running with a different version of embedded hadoop jars will fail to work in case of version incompatibilities.

- Example: AMBARI-5707, runs a embedded HBase on local FS side-by-side with cluster Hadoop installation.

- It would be good to have a hbase-env variable to completely override native lib path or a config to disable native lib path lookup, in which case user has to provide it during start.
