Siddharth Wagle commented on HBASE-13120:
-----------------------------------------
[~busbey] Renamed.
_if you just check if the string is non-zero length it'll be easier to
integrate programmatically determining if we should disable._
I initially did this but then changed to explicit check for _true_ in order to
leave only a single case for disable and regular behavior for all other cases,
for example someone doing a HBASE_DISABLE_HADOOP_CLASSPATH_LOOKUP="false" and
the lookup still getting disabled.
> Allow disabling hadoop classpath and native library lookup

> - 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.
