Harsh J commented on HBASE-4705: -------------------------------- I apologize for missing the whole activity on HBASE-4680. I think a better fix would have been, instead of the HBASE-4680, to just catch other exceptions (which is something I missed despite commenting). This change is fine too, but has lead to HBASE-4705 scenarios. Could we revert HBASE-4680 and instead add a: {code} catch (Safemode) { return true; } catch (Others) { ignore; } {code} Kinda block, while still operating on the only dir guaranteed to exist (/ - root)? This is so cause safemode is always checked first on the server side before anything else is returned. The superuser check is not client side. > HBase won't initialize if /hbase is not present > ----------------------------------------------- > > Key: HBASE-4705 > URL: https://issues.apache.org/jira/browse/HBASE-4705 > Project: HBase > Issue Type: Bug > Reporter: Harsh J > > {code} > 2011-10-31 00:09:09,549 FATAL org.apache.hadoop.hbase.master.HMaster: > Unhandled exception.
