[jira] [Commented] (BIGTOP-358) now that hadoop packages have been split we have to update the dependencies on the downstream packages

    [ https://issues.apache.org/jira/browse/BIGTOP-358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13188890#comment-13188890 ] 

Bruno Mahé commented on BIGTOP-358:
-----------------------------------

First thought would be to decouple mapreduce/yarn from hdfs then. Make hdfs or any other filesystem for hadoop provide a virtual provide such as hadoop-filesystem and make mapreduce/yarn depend on it. So if a downstream project only depend on mapreduce/yarn api, it does not have to pull hdfs if it's not needed.

> This is actually slightly more complicated than it sounds: it is pretty straightforward to replace a dependency on hadoop with a dependency on hadoop-mapreduce it is less clear what to do with HDFS. Strictly speaking HDFS is not a hard dependency (one can run on a local filesystems just fine).
