John Sichi commented on HIVE-2155:
----------------------------------
I added *'s on a bunch of places that should be using the new "Encountered
near" phrasing.
Also, the fugliness is still there for the GROUP BY stuff. Those internal
nodes should never be printed at all. Did you look into trying to get it to
print the column instead of the table?

> Follow-up to HIVE-1731.
> A number of issues raised in HIVE-1731 were caused by SemanticAnalyzer not
> reporting errors correctly.
> Specifically, the following issues need to be addressed:
> - Line numbers are not always provided and sometimes emitted as (0:-1), which
> is useless
> - Insufficient or unclear context strings are provided
> Specific issues described in HIVE-1731:
> FAILED: Error in semantic analysis: Schema of both sides of union should
> match: destinationid:_col1 _col2
> * No line/col numbers, context strings provide internal aliases instead of
> actual column names
> FAILED: Error in semantic analysis: line 0:-1 Both Left and Right Aliases
> Encountered in Join time
> * Incorrect line/col number info, no context strings to describe the aliases
> encountered
> FAILED: Error in semantic analysis: AS clause has an invalid number of aliases
> * No line/col numbers, not context string to show the aliases encountered
> FAILED: Error in semantic analysis: line 1:94 Expression Not In Group By Key a
> * testcase: SELECT a.id, VAR(a.cnt) FROM mytable a
> * Context string is unhelpful, needs to provide the actual expression, not
> just the table reference
