             Summary: Unbalance chaos monkey might kill all region servers without starting them back
                 Key: HBASE-12450
                 URL: https://issues.apache.org/jira/browse/HBASE-12450
             Project: HBase
          Issue Type: Bug
            Reporter: Virag Kothari
            Assignee: Virag Kothari
            Priority: Minor


UnbalanceKillAndRebalanceAction does kill, balance and then start of region servers. But if the balance fails exception is thrown causing the region servers to not start. For me, the balance always kept on failing with socket timeout (default 1 min) as master runs one iteration of balance for 5 mins (default config). Eventually all servers are killed but never started back.
