Hi,
I have a question about Hadoop. I am a beginner and just testing Hadoop. Would like to know how a php application would benefit from this, say an application that needs to work on a large number of image files. Do I have to store the application in HDFS always, or do I just copy it to HDFS when needed, do the processing, and then copy it back to the local file system ? Is that the case with the data files too ? Once I have Hadoop running, do I keep all data & application files in HDFS always, and not use local file system storage ? Thank you.
