Tassapol Athiapinya commented on TEZ-979:
-----------------------------------------

It is for loading TestInput/TestOutput/TestProcessor configuration. In real 
cluster, one common way to pass this config is via tez-site.xml. I already 
replaced my tez-site.xml with failing config. 
{code}
<property>
<name>tez.failing-processor.do-fail.v1<name>
<value>true</value>
</property>
{code}
Now I want to run fault tolerance in real cluster with this config. Note that 
my tez-site.xml is the same file as default tez-site.xml used in the cluster. 
Is there any other way to pass the config, if I need to have only one copy of 
tez-site.xml in my cluster?

> Allow FaultToleranceTestRunner to read default config when custom config is

> I have an environment when I run FaultToleranceTestRunner with no argument. I 
> set tez-site.xml in default path in hadoop class path. 
> FaultToleranceTestRunner cannot pick it up.
> The cause should be because of false parameter at:
> {code}
> Configuration testConf = new Configuration(false);
> {code}
