Subject [jira] [Commented] (HDFS-8213) DFSClient should use hdfs.client.htrace HTrace configuration prefix rather than hadoop.htrace
Date Fri, 01 May 2015 02:12:06 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14522663#comment-14522663
] 

Colin Patrick McCabe commented on HDFS-8213:
--------------------------------------------

findbugs warning is bogus.  patch doesn't modify org.apache.hadoop.hdfs.DataStreamer$LastException.
 the rest of the stuff looks bogus as well, guess it's time to re-run again

> 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.
