[jira] [Created] (HDFS-10925) Cache symlinkString in INodeSymlink

Yiqun Lin created HDFS-10925:
--------------------------------

             Summary: Cache symlinkString in INodeSymlink
                 Key: HDFS-10925
                 URL: https://issues.apache.org/jira/browse/HDFS-10925
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Yiqun Lin
            Assignee: Yiqun Lin
            Priority: Minor


In {{INodeSymlink}}'s construct method, it will transfer the input symlink string to a byte array. If we want to invoke {{INodeSymlink#getSymlinkString}}, it will transfer the byte array to the string again. Since we don't cache symlinkString  here, it will do the {{DFSUtil.bytes2String}} method every time. It seems not efficient.
