> Key: HDFS-4046
> URL: https://issues.apache.org/jira/browse/HDFS-4046
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: data-node, name-node
> Affects Versions: 2.0.0-alpha
> Reporter: Binglin Chang
> Assignee: Binglin Chang
> Priority: Minor
> Fix For: 3.0.0, 2.0.3-alpha
>
> Attachments: HDFS-4046-ChecksumType-NULL-and-TestAuditLogs-bug.patch,
> HDFS-4046-ChecksumType-NULL.patch, HDFS-4096-ChecksumTypeProto-NULL.patch
>
>
> I tried to write a native hdfs client using protobuf based protocol, when I
> generate c++ code using hdfs.proto, the generated file can not compile,
> because NULL is an already defined macro.
> I am thinking two solutions:
> 1. refactor all DataChecksum.Type.NULL references to NONE, which should be
> fine for all languages, but this may breaking compatibility.
> 2. only change protobuf definition ChecksumTypeProto.NULL to NONE, and use
> enum integer value(DataChecksum.Type.id) to convert between ChecksumTypeProto
> and DataChecksum.Type, and make sure enum integer values are match(currently
> already match).
> I can make a patch for solution 2.
