might as well use webhdfs these days
Yeah, this is a place where punctuation in the title makes a big difference. Can we put the exclamation point (or substitute a period) back into the title?
Agreed, this looks like a third technology named Err (perhaps a Bayesian-focused offshoot of 'R'?) is involved somehow.
Took me a while to figure it out too. I think the title would have been best written as "Hadoop and Go".
Its maybe because I'm new to the language, but I have to add 'lang' to all my Google searches for Go documentation/tips, otherwise the keywords are almost always misinterpreted.

Pros (vs Snakebite):
* C, not Python. More portable to non-Python languages; probably faster
* Speaks v1 of the protocol (AFAIK, nothing else does this except via JNI to hadoop's Java client)
* Kerberos authentication supported (but not datanode tokens or the digest auth they employ)
Cons:
* Sort of abandonware. I don't personally use HDFS anymore, so it has stagnated.
* As an extension of the above, doesn't support the v2 (Protobuf-based) protocol
* C, not Python. All the usual potential issues with C that Python shields you from.
