Hello, I am trying to learn Hadoop and doing a project on it.
I need to update some files in my project and hence wanted to use version 0.21.0 However, I am confused as to how I can compile my programs on version 0.21.0 as it doesn't have any hadoop-core-0.21.0.jar file. What option should I have to give in the -classpath option? I can see three different JAR files namely hadoop-common-0.21.0.jar, hadoop-hdfs-0.21.0.jar & hadoop-mapred-0.21.0.jar. I am getting compilation errors which using the the common jar file. Also I would like to learn the FileContext Library as the docs that I have read says that it has a simpler interface than the FileSystem. However, I cannot find any links to some example code which can help me to grasp the API. Request you to kindly share any link / code snippet to demonstrate the use of the new API. Many thanks in advance for your kind response. Warm regards Arko
