I am learning Hadoop. As a part of that, Hdfs - Hadoop distributed file system has commands similar to unix where we can create,copy,move files from unix/linux file system to HDFS.
My question is
1) how two file systems (unix and hdfs) can coexist on thr same partition..
2)What if block used by one FS is overwritten/ modified by another FS.
3) Who does this block handling mechanism inorder to avoid unwanted results.
4) what happens to inodes(unix) pointing to data blocks being used/blocked by HDFS.
Please explain what happens at atomic level when mutiple file systems coexists on same partition.
