HI, During my further testing of my Yarn Application, I am in the scenario where I was accessing HDFS path for data access using multiple nodes. I understand that HDFS is not posix compliant and so accessing HDFS data using normal Java IO api's, I have to mount HDFS to userspace. For this, there are couple of options like HDFS-Fuse or NFS. Is there any other recommended option with recent release which works better with Yarn specific application? Or with yarn applications, which one is preferred a) HDFS-Fuse or b) NFS ?
