> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: hdfs
> Reporter: Daryn Sharp
> Assignee: Daryn Sharp
> Fix For: 2.8.0, 2.9.0, 3.0.0-alpha1
>
> Attachments: HDFS-10673-branch-2.7.00.patch, HDFS-10673.1.patch,

>
>
> The INodeAttributeProvider and AccessControlEnforcer features degrade
> performance and generate excessive garbage even when neither is used. Main
> issues:
> # A byte[][] of components is unnecessarily created. Each path component
> lookup converts a subrange of the byte[][] to a new String[] - then not used
> by default attribute provider.
> # Subaccess checks are insanely expensive. The full path of every subdir is
> created by walking up the inode tree, creating a INode[], building a string
> by converting each inode's byte[] name to a string, etc. Which will only be
> used if there's an exception.
> The expensive of #1 should only be incurred when using the provider/enforcer
> feature. For #2, paths should be created on-demand for exceptions.
