Steve Loughran commented on HADOOP-14963:
-----------------------------------------
Why not create an uber-JIRA, "instrument the object stores" & link the others
to it...theres' one for S3A too. It'd be good to have a constants file
somewhere for the names of the operations, etc.
any helper classes needed to simplify this. I was thinking of a
try-with-resources wrapper
{code}
try(HTracer trace=new HTracer("getFileStatus()") {
return innerGetFileStatus(path);
}
{code}
Be interesting to see if we can use this in testing
> Add HTrace to ADLS connector

> Key: HADOOP-14963
> URL: https://issues.apache.org/jira/browse/HADOOP-14963
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/adl
> Affects Versions: 2.8.0
> Reporter: John Zhuge
>
> Add Apache HTrace support to Hadoop ADLS connector in order to support
> distributed tracing.
> Make sure the connector and the ADLS SDK support B3 Propagation so that
> tracer/span IDs are sent via HTTP request to ADLS backend.
> To build an entire distributed tracing solution for ADLS, we will also need
> these components:
> * ADLS backend should support one of the Tracers. See
> http://opentracing.io/documentation/pages/supported-tracers.html.
> * Zipkin Collector: Event Hub
> * Zipkin Storage: MySQL
