  Please add some comments explaining what it is that you're testing, 
  e.g. why is this a negative test? Why is expected to fail?

why is this a negative test? Why is expected to fail?
should i put a positive test on a negative test dir? Should we explain all test 
cases in client negative dir?
Come on, please put some positive suggestions.

https://reviews.apache.org/r/665/#comment1187

Besides describing the effect of this configuration property, can you also 
please explain the motivation? Why would the user want to set this to true? Is 
there a valid reason for setting it to false?



trunk/ql/src/test/queries/clientnegative/alter_merge_index.q
https://reviews.apache.org/r/665/#comment1183

 Should we explain all test cases in client negative dir?

Emphatically yes!

And since I'm a helpful person I'll even write the comment for you:

Verify that an error is thrown if the user attempts to concatenate an 
indexed table when hive.exec.concatenate.check.index=true

Also, please explicitly set hive.exec.concatenate.check.index=true at the 
beginning of this test.

Also, please change the name of this file and the name of the table so that 
it matches the semantics of the ALTER TABLE command, i.e. 
alter_concatenate_indexed_table.q and src_rc_concatenate_test.



trunk/ql/src/test/queries/clientpositive/alter_merge_index.q
https://reviews.apache.org/r/665/#comment1186

How about this:

* Verify that an indexed table can be concatenated when 
hive.exec.concatenate.check.index=false.

* Verify that a partitioned table can be concatenated when 
hive.exec.concatenate.check.index=false.

The point of the comments is help the reader distinguish between details 
that are relevant to the intended purpose of the test from those that are not.




trunk/ql/src/test/queries/clientpositive/alter_merge_index.q
https://reviews.apache.org/r/665/#comment1188

Please replace merge with concatenate. A better name for this test 
would be alter_concatenate_indexed_table.q



trunk/ql/src/test/queries/clientpositive/alter_merge_index.q
https://reviews.apache.org/r/665/#comment1185

These tables get cleaned up automatically. Please remove the drop 
statements.

  can you make the indentation consistent with the other property 
  elements?

It shows the same indentation on my local. So it might just be an review board 
display issue.

  So after adding this, does the block-level merge after INSERT OVERWRITE 
  be automatically supported?

No. Not automatically supported. We still need to do some work there. but it is 
a separate issue.

The indentation looks the same in your editor because these are TABs. 
Please remove, and then configure your editor to disallow TABs.

why is this a negative test? Why is expected to fail?
