> 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
