> ABFS: Add changes for expect hundred continue header with append requests
> -------------------------------------------------------------------------
>
> Key: HADOOP-18146
> URL: https://issues.apache.org/jira/browse/HADOOP-18146
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Affects Versions: 3.3.5
> Reporter: Anmol Asrani
> Assignee: Anmol Asrani
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.4.0
>
> Time Spent: 2h 10m
> Remaining Estimate: 0h
>
> Heavy load from a Hadoop cluster lead to high resource utilization at FE
> nodes. Investigations from the server side indicate payload buffering at
> Http.Sys as the cause. Payload of requests that eventually fail due to
> throttling limits are also getting buffered, as its triggered before FE could
> start request processing.
> Approach: Client sends Append Http request with Expect header, but holds back
> on payload transmission until server replies back with HTTP 100. We add this
> header for all append requests so as to reduce.
> We made several workload runs with and without hundred continue enabled and
> the overall observation is that :-
> # The ratio of TCP SYN packet count with and without expect hundred continue
> enabled is 0.32 : 3 on average.
> # The ingress into the machine at TCP level is almost 3 times lesser with
> hundred continue enabled which implies a lot of bandwidth save.
