> ABFS: Misreporting Retry Count for Sub-sequential and Parallel Operations
> -------------------------------------------------------------------------

>                 Key: HADOOP-18872
>                 URL: https://issues.apache.org/jira/browse/HADOOP-18872
>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: build
>    Affects Versions: 3.3.6
>            Reporter: Anmol Asrani
>            Assignee: Anuj Modi
>            Priority: Major
>              Labels: Bug, pull-request-available
>
> There was a bug identified where retry count in the client correlation id was 
> wrongly reported for sub-sequential and parallel operations triggered by a 
> single file system call. This was due to reusing same tracing context for all 
> such calls.
> We create a new tracing context as soon as HDFS call comes. We keep on 
> passing that same TC for all the client calls.
> For instance, when we get a createFile call, we first call metadata 
> operations. If those metadata operations somehow succeeded after a few 
> retries, the tracing context will have that many retry count in it. Now when 
> actual call for create is made, same retry count will be used to construct 
> the headers(clientCorrelationId). Alhough the create operation never failed, 
> we will still see retry count from the previous request.
> Fix is to use a new tracing context object for all the network calls made. 
> All the sub-sequential and parallel operations will have same primary request 
> Id to correlate them, yet they will have their own tracing of retry count.
