Since we do relocateRegion() calls everytime we want to relocate a region (region moved, RS down, etc) this implies that when the master is down, the some of the clients for uncached regions will be affected. > See HBASE-7767 and HBASE-11974 for some more background. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
