Example 2 with FSINFO3Request

use of org.apache.hadoop.nfs.nfs3.request.FSINFO3Request in project hadoop by apache.

the class TestRpcProgramNfs3 method testFsinfo.

@Test(timeout = 60000)

    HdfsFileStatus status = nn.getRpcServer().getFileInfo("/tmp/bar");
    long dirId = status.getFileId();
    FileHandle handle = new FileHandle(dirId);
    XDR xdr_req = new XDR();
    FSINFO3Request req = new FSINFO3Request(handle);
    req.serialize(xdr_req);
    // Attempt by an unpriviledged user should fail.
    FSINFO3Response response1 = nfsd.fsinfo(xdr_req.asReadOnlyWrap(), securityHandlerUnpriviledged, new InetSocketAddress("localhost", 1234));
    assertEquals("Incorrect return code:", Nfs3Status.NFS3ERR_ACCES, response1.getStatus());
    // Attempt by a priviledged user should pass.
    FSINFO3Response response2 = nfsd.fsinfo(xdr_req.asReadOnlyWrap(), securityHandler, new InetSocketAddress("localhost", 1234));
    assertEquals("Incorrect return code:", Nfs3Status.NFS3_OK, response2.getStatus());
