> Issue Type: Improvement
> Components: hdfs-client
> Reporter: Xiaoqiao He
> Assignee: Xiaoqiao He
> Priority: Major
>
> Recently, I meet corner case that client wait for data to be acknowledged by pipeline over 9 hours. After check branch trunk, I think this issue still exist. So I propose to add threshold about wait timeout then fail fast.
