I meant that the file system is presented in a Linux distro as kernel module. HDFS, as you know, is an alien Java process that creates a layer indirection on top of say ext4 or jfs to provide a distributed storage; Ceph does this similarly to other _native_ file systems. > And can you elaborate on why Gluster doesn't make sense as a HDFS > replacement to you? What I wanted to express, perhaps a bit clumsy, is that HDFS and Gluster are two instances of HCFS. from Ignite standpoint replacing one with another doesn't give much advantage (unless I am missing something about the Gluster).
