Hi, I browsed through the ambari source code and I was looking for code on how Ambari pulls out data for HDFS/Map reduce information.
I was looking at the ambari source code in the ambari-server directory to find how ambari interacts with hadoop and was searching for hadoop related classes in the imports section. But I could not find none. Can somebody let me know on how ambari connects to Hdfs or Map reduce. I am sure there has to be some class imports of hadoop related classes. Thanks in advance.
