[jira] Updated: (PIG-1610) 'union onschema' does handle some cases involving 'namespaced' column names in schema

2010-09-15 Thread Thejas M Nair (JIRA)

Thejas M Nair updated PIG-1610:

  Status: Patch Available  (was: Open)
Release Note: 
This fixes the behavior for merging of column alias name that have a 
'namespace' portion in them.

- Alias such as 'nm::c1' and 'c1' in two separate relations specified in 'union 
onschema' are considered mergeable and in the schema of the union, the merged 
column alias will be 'c1'. 
- Alias such as 'nm1::c1' and 'nm2::c1' in two separate relations specified in 
'union onschema'  will not be merged together, in schema of the union there 
will be two columns with these names.

Example -

> describe f;
f: {l1::a: int, l1::b: int, l1::c: int}
> describe l1;
l1: {a: int, b: int}

> u = union onschema f,l1;
> desc u;
u: {a: int, b: int, l1::c: int}

Test-patch and unit test cases have succeeded.
