> SOLR-11063 added disk space hint to Policy. The ADDREPLICA, MOVEREPLICA,
> SPLITSHARD and REPLACENODE APIs can provide this hint.
> # ADDREPLICA can query the size of the leader's data direcoty for the same
> shard and pass it to policy
> # MOVEREPLICA again knows the size of the replica being moved
> # SPLITSHARD knows the size of the split indexes before it calls addreplica
> to create replicas of the sub-shards
> # REPLACENODE can compute the sum of disk usage of all the replicas' data
> directories
> We should probably include both index and tlog size in the hint to ensure
> that we have ample space on target nodes.
> We should also take care of HDFS because for movereplica and replacenode,
> there are no disk space requirements because the original replica's HDFS data
> and ulog directories are used by the new replicas.
