> 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.
