Andrew Wang commented on HADOOP-11804:
--------------------------------------
Thanks for the quick response Sean,
bq. I'm confused about test protobuf classes showing up in the client-api jar...
Yea, this was a mystery to me too. Could be PEBKAC, in which case I'd
appreciate fuller build instructions.
bq. I think the answer for the logging libraries and htrace is to leave them
unshaded, since it's common to want to modify logging settings and to want to
trace through e.g. the hdfs client. Would like some feedback here.
The logging rationale here sounds good to me. We've been trying to migrate
things to slf4j, but evidently we haven't made much progress.
Unshading HTrace also sounds good, since I'm guessing that shading will mess up
tracing from an app into the Hadoop client. [~cmccabe] care to comment more
authoritatively?
