Santhosh Srinivasan updated PIG-158:
------------------------------------
Attachment: parser_changes_v1.patch
I have attached version 1 of the parser changes. The status of testing:
[junit] Running org.apache.pig.test.TestLogicalPlanBuilder
[junit] Tests run: 54, Failures: 10, Errors: 1, Time elapsed: 0.697 sec
Out of the 10 Failures,
- 8 are due to the pigInstantiateFunc,
- 1 is due to a javacc bug as noted in the comments in the test case
- 1 is due to the :: disambiguator not being in place. The :: disambiguator is
used when multiple columns have the same alias due to flattening.
The 1 Error is due to the exectype local being commented out in PigContext
This patch is to unblock the logical layer to physical layer translation.
TODO:
1. Add the schema flattening feature
2. Convert the log.info to log.debug and log.trace
3. Make the logger static
