> Right now HoS only use a few error codes. For the majority of the errors, user will see
an error code 1 followed by a lengthy stacktrace. This is not ideal since:
> 1. It is often hard to find the root cause - sometimes it is hidden deeply inside the
stacktrace.
> 2. After identifying the root cause, it is not easy to find a fix. Often user have to
copy & paste the error message and google them. 
> 3. It is not clear whether the error is transient or not, depending on which user may
want to retry the query. 
> To improve the above, this JIRA propose to assign error code & canonical error messages
for different HoS errors. We can take advantage of the existing {{ErrorMsg}} class.
