             Summary: Whether checking path access permissions should be decided by dfs.permissions.enabled in concat operation
                 Key: HDFS-16983
                 URL: https://issues.apache.org/jira/browse/HDFS-16983
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: 3.4.0
            Reporter: caozhiqiang
            Assignee: caozhiqiang


In concat RPC, it will call FSDirConcatOp::verifySrcFiles() to check the source files. In this function, it would make permission check for srcs. Whether do the permission check should be decided by dfs.permissions.enabled configuration. And the 'pc' parameter is always not null.
{code:java}
// permission check for srcs
if (pc != null) {
  fsd.checkPathAccess(pc, iip, FsAction.READ); // read the file
  fsd.checkParentAccess(pc, iip, FsAction.WRITE); // for delete
} {code}
