> 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.
