I did not reply at the time this message was sent because I had
absolutely no idea. Now somebody has revived the thread, and I've
looked a little deeper.
It is not at all clear from the documentation exactly what the
'repository' parameter should be set to. By poking at the code, I was
able to figure out what you need to do.
The repository name that you specify in the URL must be specified in
solr.xml, with a config like the following. The config I included below
relies on system properties to work properly, but you could specify the
values directly in solr.xml:
<backup>
<repository name="hdfs"
class="org.apache.solr.core.backup.repository.HdfsBackupRepository">
<str name="location">${solr.hdfs.default.backup.path}</str>
<str name="solr.hdfs.home">${solr.hdfs.home:}</str>
<str name="solr.hdfs.confdir">${solr.hdfs.confdir:}</str>
<str
name="solr.hdfs.permissions.umask-mode">${solr.hdfs.permissions.umask-mode:000}</str>
</repository>
</backup>
I got that config from the Solr test class named TestHdfsBackupRestoreCore.
Once you have a complete repository config in solr.xml and restart Solr,
it should work.
Thanks,
