> Similar to writing flush events to WAL (HBASE-11511) and compaction events to WAL (HBASE-2231), we should write region open and close events to WAL. 
> This is especially important for secondary region replicas, since we can use this information to pick up primary regions' files from secondary replicas.
> However, we may need this for regular inter cluster replication as well, see issues HBASE-10343 and HBASE-9465. 
> A design doc for secondary replica replication can be found at HBASE-11183.
