Binglin Chang commented on HADOOP-9155:
---------------------------------------
Regarding HDFS-4319, I read the code of CopyToLocal, it seams it doesn't copy
fspermission from src to dest, but just use default permission, which leads to
this problem?
{code}
CommandWithDestination.java
void writeStreamToFile(InputStream in, PathData target) throws IOException {
FSDataOutputStream out = null;
try {
out = create(target);
IOUtils.copyBytes(in, out, getConf(), true);
} finally {
IOUtils.closeStream(out); // just in case copyBytes didn't
}
}
// tag created files as temp files
FSDataOutputStream create(PathData item) throws IOException {
try {
return create(item.path, true);
} finally { // might have been created but stream was interrupted
deleteOnExit(item.path);
}
}
{code}
> FsPermission should have different default value, 777 for directory and 666
> for file
