Kevin Risden updated SOLR-11473:
--------------------------------
Component/s: Hadoop Integration
> Make HDFSDirectoryFactory support other prefixes (besides hdfs:/)
> -----------------------------------------------------------------
>
> Key: SOLR-11473
> URL: https://issues.apache.org/jira/browse/SOLR-11473
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Hadoop Integration, hdfs
> Affects Versions: 6.6.1
> Reporter: Radu Gheorghe
> Priority: Minor
> Attachments: SOLR-11473.patch

> Not sure if it's a bug or a missing feature :) I'm trying to make Solr work
> on Alluxio, as described by [~thelabdude] in
> https://www.slideshare.net/thelabdude/running-solr-in-the-cloud-at-memory-speed-with-alluxio/1
> The problem I'm facing here is with autoAddReplicas. If I have
> replicationFactor=1 and the node with that replica dies, the node taking over
> incorrectly assigns the data directory. For example:
> before
> {code}"dataDir":"alluxio://localhost:19998/solr/test/",{code}
> after
> {code}"dataDir":"alluxio://localhost:19998/solr/test/core_node1/alluxio://localhost:19998/solr/test/",{code}
> The same happens for ulogDir. Apparently, this has to do with this bit from
> HDFSDirectoryFactory:
> {code} public boolean isAbsolute(String path) {
> return path.startsWith("hdfs:/");
> }{code}
> If I add "alluxio:/" in there, the paths are correct and the index is
> recovered.
> I see a few options here:
> * add "alluxio:/" to the list there
> * add a regular expression in the lines of \[a-z]*:/ I hope that's not too
> expensive, I'm not sure how often this method is called
> * don't do anything and expect alluxio to work with an "hdfs:/" path? I
> actually tried that and didn't manage to make it work
> * have a different DirectoryFactory or something else?
> What do you think?
