Mark Miller commented on SOLR-5656:
-----------------------------------
I've got a pretty nicely working patch for auto replica failover ready for this
issue. It will need some small extensions to work without a shared filesystem,
but it provides all of the ground work that we will want for that. I'll post my
current progress in a couple days.
> Add SharedFS Failover option that allows surviving Solr instances to take
> over serving data for victim Solr instances.

>
> When using HDFS, the Overseer should have the ability to reassign the cores
> from failed nodes to running nodes.
> Given that the index and transaction logs are in hdfs, it's simple for
> surviving hardware to take over serving cores for failed hardware.
> There are some tricky issues around having the Overseer handle this for you,
> but seems a simple first pass is not too difficult.
> This will add another alternative to replicating both with hdfs and solr.
> It shouldn't be specific to hdfs, and would be an option for any shared file
> system Solr supports.
