Summary: Errors in ORC Specification
Key: ORC-426
URL: https://issues.apache.org/jira/browse/ORC-426
Project: ORC
Issue Type: Bug
Components: documentation
Reporter: Fang Zheng
There are some errors in the ORC format specifications:
1. In specification/ORCv1.md and specification/ORCv2.md, the following sentence
appears twice in the description of "Patched Base”:
Data values (W * L bits padded to the byte) - A sequence of W bit positive
values that are added to the base value.
2. In specification/ORCv0.md, specification/ORCv1.md, and
specification/ORCv2.md, there is an error in the description of “Map Columns”:
Maps are encoded as the PRESENT stream and a length stream with number
of items in each list. —> The last word “list” should be changed to “map”
3. In specification/ORCv1.md and specification/ORCv2.md, the word
“BloomFilterEntry” should be changed to “bloom filter entry”, as
“BloomFilterEntry” does not exist in the source code or ProtocolBuffer
definition.
