> Implement getContentSummary(..) in HftpFileSystem
> -------------------------------------------------
>
> Key: HDFS-786
> URL: https://issues.apache.org/jira/browse/HDFS-786
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Tsz Wo (Nicholas), SZE
> Assignee: Tsz Wo (Nicholas), SZE
> Fix For: 0.22.0
>
> Attachments: h786_20091223.patch, h786_20091224.patch
>
>
> HftpFileSystem does not override getContentSummary(..). As a result, it uses
> FileSystem's default implementation, which computes content summary on the
> client side by calling listStatus(..) recursively. In contrast,
> DistributedFileSystem has overridden getContentSummary(..) and does the
> computation on the NameNode.
> As a result, running "fs -dus" on hftp is much slower than running it on hdfs.
