I am a just data analyst hails from non cs background (not a hardcore system programmer) working on linux OS. While exploiting analysis using hadoop, a question was coming to my mind that ... / is a root under which all files of your system exists in a hierarchical manner. In hadoop envirorment, a special file system called as HDFS is there which is actually meant to store huge files to be processed by hadoop programming frameworks.
hadoop -fs put localfile.txt
Although, such files should be accessible under /. so where can i see such files by using cat, less or more linux commands without prefixing hadoop -fs
If, unfortunately i get some error in hadoop/HDFS environment, then how can i acess my data which is still residing on my linux machine.
