Subject [jira] [Updated] (HADOOP-13473) TestTracing#testTracing is failing in trunk
Date Tue, 09 Aug 2016 18:30:21 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-13473?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Daryn Sharp updated HADOOP-13473:
    Attachment: HADOOP-13473.patch

The htrace span is technically violating abstractions by accessing rpc headers in the ipc
layer.  I tried to push the htrace scope down into the rpc engine/handler but that would alter
the start time semantics from when it went in the queue, to when it was extracted.  Tried
to create a span with the queue time, but htrace apis just aren't amiable to creating a scope
from the manual span.

Anyway, just added a wrapper to lazy decode the rpc header.
