Each great spirit:
I learn Hadoop, Hadoop environment has been set up complete, can pass the HDFS file command line for operation, but want to write Java code calls the HDFS API, do not know how to start, the website has been can't find the corresponding examples, only to find the Java API, through the baidu search the BBS post, there are a variety of examples, but always feel that not enough authority, who is a great god can tell where I can find a Java actions under the authority of the HDFS data?

Thank you very much!
