[jira] [Updated] (HIVE-2155) Improve error messages emitted during
semantic analysis
[ https://issues.apache.org/jira/browse/HIVE-2155?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Syed S. Albiz updated HIVE-2155:
--------------------------------
Attachment: HIVE-2155.1.patch
This patch (review board still not accepting new registrations) attaches line/column number to the vast majority of SemanticExceptions thrown. In addition, the context strings for the error messages relating to UNION ALLs and GROUP BY keys have been changed to provide more meaningful context

> 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
