Colin Patrick McCabe commented on HDFS-4864:
--------------------------------------------
fuse_impls_open.c: remove deadcode that was causing compiler warning messages
fuse_impls_rename.c: use hdfsRenameExt with HDFS_RENAME_FLAG_OVERWRITE
hdfs.c / hdfs.h: add hdfsRenameExt, which takes a flags argument. This
argument allows you to specify HDFS_RENAME_FLAG_OVERWRITE, to get the behavior
that rename overwrites the destination if it exists as a file.
jni_helper.c: add getJavaEnum, to help with manipulating the {{Options$Rename}}
enum
test_libhdfs_threaded.c: test hdfsRenameExt (actually, this is the first rename
test we have in there)
> fuse_dfs's rename can't rename over a file

> {{fuse_dfs}}'s rename can't rename over a file, which causes a lot of stuff
> to not work, including {{rsync}}. It should be simple enough for libhdfs to
> provide a method that calls {{FileSystem#rename}} with the 'overwrite' option.
