Yiqun Lin updated HDDS-3058:
----------------------------
Status: Patch Available (was: Open)
> OzoneFileSystem should override unsupported set type FileSystem API
> -------------------------------------------------------------------
>
> Key: HDDS-3058
> URL: https://issues.apache.org/jira/browse/HDDS-3058
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: Ozone Filesystem
> Affects Versions: 0.4.1
> Reporter: Yiqun Lin
> Assignee: Yiqun Lin
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Currently, OzoneFileSystem only implements some common useful FileSystem APIs
> and most of other API are not supported and inherited from parent class
> FileSystem by default. However, FileSystem do nothing in some set type
> method, like setReplication, setOwner.
> {code:java}
> public void setVerifyChecksum(boolean verifyChecksum) {
> //doesn't do anything
> }
> public void setWriteChecksum(boolean writeChecksum) {
> //doesn't do anything
> }
> public boolean setReplication(Path src, short replication)
> throws IOException {
> return true;
> }
> public void setPermission(Path p, FsPermission permission
> ) throws IOException {
> }
> public void setOwner(Path p, String username, String groupname
> ) throws IOException {
> }
> public void setTimes(Path p, long mtime, long atime
> ) throws IOException {
> }
> {code}
> This set type functions depend on the sub-filesystem implementation. We need
> to to throw unsupported exception if sub-filesystem cannot support this.
> Otherwise, it will make users confused to use hadoop fs -setrep command or
> call setReplication api. Users will not see any exception but the command/API
> can execute fine. This is happened when I tested for the OzoneFileSystem via
> hadoop fs command way.
