Colin Patrick McCabe commented on HDFS-8358:
--------------------------------------------
bq. I would like to make TraceAdmin able to handle other config prefix such as
"yarn.htrace.". I think SpanReceiverHost#addSpanReceiver is the right place to
deal with the configs without prefix. Anyway we should file a new JIRA for that.
Yeah. The user should be able to set
"-Clocal-file-span-receiver.path=/tmp/foo" on the YARN daemons and have it
apply the relevant YARN htrace properties. There isn't any need to require the
user to send '-Cyarn.htrace.local-file-span-receciver.path=...' We know that
YARN tracing is what we want to configure, by virtue of the fact that the
\-host argument was for a YARN host.
bq. The failure of TestHdfsConfigFields will be fixed in HDFS-8371. It should
be addressed as separate JIRA and I will update the patch once HDFS-8371 is
committed.
OK.
+1 for v3, can you file a follow-on JIRA to talk about the prefix issue?
