Subject: Re: Exception while using HBase trunk with hadoop - 2.0.3

The exception was from hadoop layer - when waiting to get out of safe mode.
Here is the call:

    } catch (Exception e) {

      if (e instanceof IOException) throw (IOException) e;      // Check
whether dfs is on safemode.

      inSafeMode = dfs.setSafeMode(

        org.apache.hadoop.hdfs.protocol.FSConstants.SafeModeAction.
SAFEMODE_GET);
I wish we had logged the exception prior to the call. Looks like
setSafeMode() with boolean parameter is not supported.

Cheers
