Chesnay Schepler commented on FLINK-15544:
------------------------------------------
Have you done any tests to verify the compatibility of later httpcore versions
with the currently used httpclient version?
httpcore is used by _a lot_ of Flink components, so we'd have to be very
careful when changing this.
In any case I would recommend to not have your projects use flink-parent as a
parent; had you just bundled a later httpcore version in your jar you'd never
have run into this issue.
> Upgrade http-core version to avoid potential DeadLock problem

> Key: FLINK-15544
> URL: https://issues.apache.org/jira/browse/FLINK-15544
> Project: Flink
> Issue Type: Bug
> Components: Build System
> Reporter: Terry Wang
> Priority: Major
>
> Due to the bug of http-core:4..46 (we current use) HTTPCORE-446, it may cause
> the bug of deadLock, we should upgrade the version.
> Background:
> We have a custom connector whose parent project is flink-parent, which cause
> the dependency of all connector sdk's http-client version and http core
> version become consistent with the version in DependencyManagement section.
> It costs us a lot to debug the problem due to HTTPCORE-446 in our production
> environment.
