----------------------------------
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.
