> Enhance distcp to handle *http* as a 'source protocol'.
> -------------------------------------------------------
>
> Key: HADOOP-341
> URL: http://issues.apache.org/jira/browse/HADOOP-341
> Project: Hadoop
> Issue Type: Improvement
> Components: util
> Reporter: Arun C Murthy
> Assigned To: Arun C Murthy
> Fix For: 0.5.0
>
> Attachments: distcp.patch, distcp2.patch, distcp_input_uri.patch
>
>
> Requirements:
> Presently distcp recursively copies a directory from one dfs to another i.e. both source
and destination of of the *dfs* protocol.
> Enhance it to handle *http* as the source protocol i.e. support copying files from
arbitrary http-based sources into the dfs.
> Design:
>
> Follow distcp's current design: one map task per file which needs to be copied.
> Caveat: distcp handles *recursive* copying by listing sub-directories; this is not
as feasible with a http-based source since things like 'fancy-indexing' might not be enabled
on the web-server (for all sub-locations recursively too), and even if it is enabled it will
mean tedious parsing of the html served to glean the sub-directories etc. Hence the idea is
to support an input file (via a -f option) which contains a list of the http-based urls which
represent multiple source files.
