=Description=
Apache Hadoop provides a high performance native protocol for accessing HDFS. While this is great for Hadoop applications running inside a Hadoop cluster, users often want to connect to HDFS from the outside. For examples, some applications have to load data in and out of the cluster, or to interact with the data stored in HDFS from the outside. Of course they can do this using the native HDFS protocol but that means installing Hadoop and a Java binding with those applications. To address this we have developed an additional protocol to access HDFS using an industry standard RESTful mechanism, called WebHDFS. As part of this, WebHDFS takes advantages of the parallelism that a Hadoop cluster offers. Further, WebHDFS retains the security that the native Hadoop protocol offers. It also fits well into the overall strategy of providing web services access to all Hadoop components.
