Subject [jira] [Created] (HADOOP-17238) Add ViewFileSystem/InodeTree Mount points Resolution Cache
Date Wed, 02 Sep 2020 02:07:00 GMT
zhenzhao wang created HADOOP-17238:

             Summary: Add  ViewFileSystem/InodeTree Mount points Resolution Cache
                 Key: HADOOP-17238
                 URL: https://issues.apache.org/jira/browse/HADOOP-17238
             Project: Hadoop Common
          Issue Type: Improvement
          Components: viewfs
            Reporter: zhenzhao wang
            Assignee: zhenzhao wang

Now the ViewFileSystem walkthrough InodeTree to resolve the passed-in path. This could be
optimized by adding a cache of resolution result. It will benefit all kinds of mount points.
And it is also very useful to reduce the Regex parse cost of Regex Mount points introduced
in HADOOP-15891
