Subject Re: The configuration loading behavior
Date Thu, 29 Sep 2011 01:40:44 GMT
hmm ... I tried a small test program, if I put log4j configuration in the
classpath and turn on debug level, I am actually seeing the exception
thrown. The seemingly silly issue I had have been bugging me for a while.


DEBUG hadoop.conf.Configuration - java.io.IOException: config()
    at org.apache.hadoop.conf.Configuration.<init>(Configuration.java:226)
    at org.apache.hadoop.conf.Configuration.<init>(Configuration.java:213)
