Nearly all Apache Accumulo instances are configured to send traces to themselves using this mechanism. There's a tracer process that spans are sent to via Thrift, and the tracer inserts the spans into Accumulo. The tracer location(s) are discovered via ZooKeeper. So, pretty normal? https://github.com/apache/accumulo/tree/master/server/tracer/src/main/java/org/apache/accumulo/tracer When testing out HDFS and Accumulo tracing together, I found I had to add a configuration property that would optionally allow the receiver to drop spans of length 0ms, as HDFS was generating a huge number of these. (I realize dropping spans is not recommended, but I was still able to do some interpretation of parentless spans when the 0ms spans were missing.)
