Filesystems - Yes. You can use NFS/Local FSes for MR. Check this link for an example of a non-HDFS FS in use: http://old.nabble.com/Hadoop-over-Lustre--td19092864.html (Solution's down the thread)
DataBases - No. Not directly AFAIK. However you can write custom sources (and perhaps sinks) for it for use within MR jobs.
