Srikanth Srungarapu commented on HBASE-13403:
---------------------------------------------

Are you okay with defaulting this to 10 seconds or do you think we should go for better defaulting?
{code}
+    FSUtils.waitOnSafeMode(c, c.getInt(HConstants.MASTER_WAIT_ON_SAFE_MODE, 10 * 1000));
{code}

> We currently wait whatever is the configured value of hbase.server.thread.wakefrequency or the default 10 seconds. We should have a configuration to control how long we wait until the HDFS is no longer in safe mode, since using the existing hbase.server.thread.wakefrequency property to tune that can have adverse side effects. My proposal is to add a new property called hbase.master.waitonsafemode and start with the current default.
