Xi Wang commented on AMBARI-5197:
---------------------------------

Added a new property in tez-site.xml:
{code}<property>
    <name>tez.am.env</name>
    
<value>LD_LIBRARY_PATH=/usr/lib/hadoop/lib/native:/usr/lib/hadoop/lib/native/`$JAVA_HOME/bin/java
 -d32 -version &amp;&gt; /dev/null;if [ $? -eq 0 ]; then echo Linux-i386-32; 
else echo Linux-amd64-64;fi`</value>
    <description>
        Additional execution environment entries for tez. This is not an 
additive property. You must preserve the original value if
        you want to have access to native libraries.
    </description>
  </property>
{code}
The value of tez.am.env is exactly the same as mapreduce.admin.user.env.

> This is to ensure LD_LIBRARY_PATH or its equivalent is setup correctly to 
> ensure native libs are loaded properly.
