[jira] Created: (HADOOP-4028) re-factor fuse-dfs into fuse specific
things and a more posix-like layer on top of libhdfs
re-factor fuse-dfs into fuse specific things and a more posix-like layer on top of libhdfs
------------------------------------------------------------------------------------------
Key: HADOOP-4028
URL: https://issues.apache.org/jira/browse/HADOOP-4028
Project: Hadoop Core
Issue Type: Improvement
Components: contrib/fuse-dfs
Reporter: Pete Wyckoff
Priority: Minor
libhdfs is now very hadoop specific, which is good since there are many hadoop attributes not present in things like stat structures. but, for things that want to access hdfs as a posix-like FS, they would benefit from a more standard API.
fuse-dfs now does this itself, translating from hadoop specific structures from hadoop to posix structures like stat. Let's put a layer on top of libhdfs that does this for us so others benefit from it. Once stable, we can look at adding it to libhdfs as a libhdfs_posix_like.so or something.

[jira] Commented: (HADOOP-4028) re-factor fuse-dfs into fuse
specific things and a more posix-like layer on top of libhdfs

Craig Macdonald commented on HADOOP-4028:
-----------------------------------------
I'm hoping to get back to the permissions stuff in libhdfs in October (post PhD thesis). Once this is in place, it should be should be straightforward to add the posix permissions API around libhdfs.
