[jira] [Commented] (HIVE-2155) Improve error messages emitted during semantic analysis

John Sichi commented on HIVE-2155:

One comment:  Hive currently has this strange convention where it appends a 
context token onto an error message, without always explaining how it relates 
to the error.  For example, 

{noformat}
In strict mode, if ORDER BY is specified, LIMIT must also be specified 'key'
{noformat}

Here the 'key' on the end is really confusing.  It should be something like

{noformat}
In strict mode, if ORDER BY is specified, LIMIT must also be specified; error 
encountered near token 'key'
{noformat}

This patch increases the number of places where we do this, so I think we need 
to improve the existing convention as part of it.  I'm not sure if the 
suggestion above is generic enough.

Ashutosh, ant package builds properly. But ant test fails with compilation

mapred vs mapreduce

[John Sichi]

An interesting fact I picked up at the Hadoop Hackathon today was that the 
mapred API has been "undeprecated".  This means that it may be OK to just leave 
Hive on the old mapred API and spend cleanup energy elsewhere.

Review request for hive and John Sichi.


Summary
---

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.


This addresses bug HIVE-2155.

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

> - 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

Updated the patch to do prefix matching and added a testcase.


Summary

Attached patch generates a single M/R job for multi group by query with 
non-null common group by key set. Added configuration 
hive.multigroupby.singlemr to turn on and off the optimization.
