Matteo Bertozzi commented on HBASE-13217:
-----------------------------------------
{quote}The cluster has 3 region servers. table1 has 2 regions, one hosted on
rs1 and one hosted on rs2.
When the master procedure is issued, all region servers will be triggered.
Master only waits for rs1 and rs2 to check in.
But rs3 will report in as well, but of course its vote will be ignored.{quote}
unless the code is changed, rs3 doesn't do anything because he doesn't host any
region of the table.
