Wei-Chiu Chuang commented on HADOOP-13353:
------------------------------------------
I see that when the IOException is thrown, the log message does not preserve
its stacktrace. Could you also update the fix to include the stacktrace?
Basically, change it to:
{code}
catch (IOException ioe) {
LOG.warn("Exception while trying to password for alias " + alias + ": ",
ioe);
}
{code}
> LdapGroupsMapping getPassward shouldn't return null when IOException throws
