Shubham Chopra updated PIG-161:
-------------------------------
Attachment: logToPhyTranslator.patch
Rough and incomplete first version of the logical to physical translator. Some
of the helper methods need to be fine tuned. Especially the GenPhyOp static
methods where I need to start using nodeIdGenerator instead of a random number
generator for the operators.
The important files are LogToPhyTranslationVisitor.java and
TestLogToPhyCompiler.java. Also minor modification in POGenerate and POSort
with the inclusion of get methods to obtain the plans.
Thanks Santhosh for the clarifications on LOBinCond. I'd need some more time to
write the POBinCond. I think PONegative also needs to be implemented. I'll
submit a patch for both of them asap.
