> Over in HBASE-57 we want to consider block locations for region assignment. This is most important during cluster startup where you currently lose all locality because regions are assignment randomly.
> This jira is about a shot-term solution to the cluster startup problem by retaining assignment information after a cluster shutdown and using it on the next cluster startup.
