hdfs-parquet-scanner
......................................................................


Patch Set 10:

(7 comments)

http://gerrit.cloudera.org:8080/#/c/3774/10/be/src/exec/hdfs-avro-scanner.h
File be/src/exec/hdfs-avro-scanner.h:

PS10, Line 93: Codegen parsing records, writing tuples and evaluating predicates
In light of the earlier comments indicating it's confusing that each scanner 
CodeGen implementation returns a different set of functionality, let's be more 
specific here like you were with parquet and say "Codegen DecodeAvroData()".


Line 95:   /// otherwise.
why did the explanation of the status return value go away in this comment 
since patch 9?


http://gerrit.cloudera.org:8080/#/c/3774/10/be/src/exec/hdfs-parquet-scanner.h
File be/src/exec/hdfs-parquet-scanner.h:

Line 334:   /// 'process_scratch_batch_fn' if codegen was successful or NULL 
otherwise.
same here about return status comment going missing. i think you reverted some 
part of the patch 9?


http://gerrit.cloudera.org:8080/#/c/3774/10/be/src/exec/hdfs-sequence-scanner.h
File be/src/exec/hdfs-sequence-scanner.h:

PS10, Line 170: Codegen writing tuples and evaluating predicates.
"Codegen WriteAlignedTuples()" or whatever


Line 171:   /// 'write_aligned_tuples_fn' if codegen was successful or NULL 
otherwise.
return status comment was removed here too.


http://gerrit.cloudera.org:8080/#/c/3774/10/be/src/exec/hdfs-text-scanner.h
File be/src/exec/hdfs-text-scanner.h:

Line 60:   /// Codegen writing tuples and evaluating predicates. Stores the 
resulting function in
Likewise for these say "Codegen WriteAlignedTuples()" or whatever it is 
actually doing.


Line 61:   /// 'write_aligned_tuples_fn' if codegen was successful or NULL 
otherwise.
comment was removed here too
