NAME

Net::Hadoop::WebHDFS::LWP - Client library for Hadoop WebHDFS and HttpFs, with Kerberos support

VERSION

version 0.005

SYNOPSIS

use Net::Hadoop::WebHDFS::LWP;

my $client = Net::Hadoop::WebHDFS::LWP->new(
    host        => 'webhdfs.local',
    port        => 14000,
    username    => 'jdoe',
    httpfs_mode => 1,
);
$client->create(
    '/foo/bar', # path
    "...",      # content
    permission => '644',
    overwrite => 'true'
) or die "Could not write to HDFS";

DESCRIPTION

This module is a quick and dirty hack to add Kerberos support to Satoshi Tagomori's module Net::Hadoop::WebHDFS, to access Hadoop secure clusters. It simply subclasses the original module, replacing Furl with LWP, which will transparently use LWP::Authen::Negotiate when needed. So the real documentation is contained in Net::Hadoop::WebHDFS.

ACKNOWLEDGEMENTS

As mentioned above, the real work was done by Satoshi Tagomori

Thanks to my employer Booking.com to allow me to release this module for public use
