Tsz Wo (Nicholas), SZE commented on HDFS-618:
---------------------------------------------
- new public methods needs javadoc, e.g.
{code}
+ public boolean mkdir(Path f, FsPermission permission) throws IOException {
+ return dfs.mkdirs(getPathName(f), permission, false);
+ }
{code}
- The following method in DFSClient is not used. How about we deprecate it?
{code}
public boolean mkdirs(String src) throws IOException {
- return mkdirs(src, null);
+ return mkdirs(src, null, true);
}
{code}
- This and HDFS-617 are going to conflict each other. It looks like that this
patch is simpler and may go first. BTW, could you create helper methods for
the common codes like the following?
{code}
+ if (!createParent) {
+ Path parent = new Path(src).getParent();
+ if (parent != null && !dir.isDir(parent.toString())) {
+ throw new FileNotFoundException("Can't mkdir " + src
+ + "; parent directory " + parent.toString() + " doesn't exist.");
+ }
+ }
{code}
