Colin Patrick McCabe commented on HDFS-4214:
--------------------------------------------
It's already logged by this code in OfflineEditsViewer:
{code}
...
} catch(Exception e) {
System.err.println("Encountered exception. Exiting: " + e.getMessage());
e.printStackTrace(System.err);
return -1;
}
...
{code}
I guess arguably that should catch {{Throwable}}. But even if that doesn't
happen, Java would just bubble the exception up to the top level and print it
to stderr.
> OfflineEditsViewer should print out the offset at which it encountered an
