Subject [jira] [Commented] (HBASE-13120) Allow disabling hadoop classpath and native library lookup
Date Tue, 03 Mar 2015 19:42:07 GMT

Enis Soztutar commented on HBASE-13120:
---------------------------------------

[~apurtell] do you mind committing this to 1.0 as well if you want to pick it in 0.98. It
is a low risk change.

> - 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.
