Subject [jira] Created: (HADOOP-6467) Performance improvement for liststatus on directories in hadoop archives.
Date Wed, 23 Dec 2009 18:32:29 GMT
Performance improvement for liststatus on directories in hadoop archives.
-------------------------------------------------------------------------

                 Key: HADOOP-6467
                 URL: https://issues.apache.org/jira/browse/HADOOP-6467
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Mahadev konar
            Assignee: Mahadev konar
             Fix For: 0.22.0


A liststatus call on a directory in hadoop archives leads to ( 2* number of files in directory)
open calls to the namenode. This is very sub optimal and needs to be fixed to make it performant
enough to be used on a daily basis.
