[jira] [Reopened] (HBASE-16570) Compute region locality in parallel at startup

     [ https://issues.apache.org/jira/browse/HBASE-16570?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gary Helmling reopened HBASE-16570:
-----------------------------------

I've reverted this from branch-1.3 for the moment, until the issue that I described can be addressed.  I don't see where this would impact master startup time.  If we need to pre-initialize this on startup, let's do it in a background thread only on startup.  We need to make sure that locality is not recomputed on every run and that we use the cache instead.
