Subject [jira] [Commented] (HDFS-8358) TestTraceAdmin fails
Date Tue, 12 May 2015 21:12:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14540743#comment-14540743
] 

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?

failing.
> It was probably unnoticed because the jira changed and triggered unit testing in common
only.
