Todd Lipcon commented on HBASE-2363:
------------------------------------

Another example is in HLog where we swallow exceptions writing the split logs. 
Before fixing HBASE-2355 I was seeing a case where exceptions closing the 
output of log splitting were ignored and then data was silently lost (even with 
sync). I would rather have had the HMaster shut itself down.

> There are many cases in HBase when the process detects that some data is "not 
> quite right". We often have two choices: (a) throw up our hands and exit, or 
> (b) log a warning and push through the issue, potentially losing data. I 
> think some users are very sensitive to dataloss and would prefer that the 
> system become unavailable rather than continue with potentially lost data. 
> Other users just want the system to stay up, and if they lose a log segment 
> it's fine.
