Versions: Hadoop: 2.0.0-cdh4.3.1
HBase: 0.94.6-cdh4.3.1
I am running cloudera quick start vm, Here is my little remote HBase Java
client(HbaseClient.java), all it does is:
public static void main(String[] args) throws IOException {
Configuration config = HBaseConfiguration.create();
HTable table = new HTable(config, "s1");
System.out.println(table.getTableName());
}
When I run my java client, I get this error:
log4j:WARN No appenders could be found for logger
(org.apache.hadoop.metrics2.lib.MutableMetricsFactory).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig
for more info.

I debugged through the code, it's hard to find whether the client is using
my hbase-site.xml in resources folder or not. I even put wrong format
content in hbase-site.xml, Java client is getting the same error. So I
think it's not using it. Isn't resources folder part of the CLASSPATH? Is
there any way to check if the hbase-site.xml gets used, if not used, how to
get my client to use it.
