If this is a dropin replacement, a REST wrapper around the API to just take advantage of it with client bindings in random libraries could work as well. Edit: https://github.com/amplab/tachyon/blob/master/src/main/java/tachyon/UnderFileSystemHdfs.java https://github.com/amplab/tachyon/blob/master/src/main/java/... It appears to just be a thin wrapper around HDFS, so the namenode and what not probably applies here.
