While testing Solr's new ability to store data and transaction directories in HDFS I added an additional core to one of my testing servers that was configured as a backup (active but not leader) core for a shard elsewhere. It looks like this extra core copies the data into its own directory rather than just using the existing directory with the data that's already available to it.
Since HDFS likely already has redundancy of the data covered via the replicationFactor is there a reason for non-leader cores to create their own data directory rather than doing reads on the existing master copy? I searched Jira for anything that suggests this behavior might change and didn't find any issues; is there any intent to address this? Thanks, Greg
