Subject [jira] [Created] (HDFS-10768) Optimize mkdir ops
Date Tue, 16 Aug 2016 22:37:20 GMT
Daryn Sharp created HDFS-10768:
----------------------------------

             Summary: Optimize mkdir ops
                 Key: HDFS-10768
                 URL: https://issues.apache.org/jira/browse/HDFS-10768
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: hdfs
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp


Directory creation causes excessive object allocation: ex. an immutable list builder, containing
the string of components converted from the IIP's byte[]s, sublist views of the string list,
iterable, followed by string to byte[] conversion.  This can all be eliminated by accessing
the component's byte[] in the IIP.
