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}

> Make waitOnSafeMode configurable in MasterFileSystem

> 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.
