Billie Rinaldi commented on HDFS-8213:
--------------------------------------
I agree, having DFSClient use a separate configuration key seems like it would
satisfy all the issues we've discussed. Thanks for coming up with a solution
that works for both of us, [~cmccabe].
> DFSClient should not instantiate SpanReceiverHost

> Key: HDFS-8213
> URL: https://issues.apache.org/jira/browse/HDFS-8213
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.7.0
> Reporter: Billie Rinaldi
> Assignee: Brahma Reddy Battula
> Priority: Critical
>
> DFSClient initializing SpanReceivers is a problem for Accumulo, which manages
> SpanReceivers through its own configuration. This results in the same
> receivers being registered multiple times and spans being delivered more than
> once. The documentation says SpanReceiverHost.getInstance should be issued
> once per process, so there is no expectation that DFSClient should do this.
