László Bodor updated TEZ-4527:
------------------------------
Fix Version/s: 0.10.5
> Add generic and pluggable hooks for DAGs and task attempts
> ----------------------------------------------------------
>
> Key: TEZ-4527
> URL: https://issues.apache.org/jira/browse/TEZ-4527
> Project: Apache Tez
> Issue Type: New Feature
> Reporter: Shohei Okumiya
> Assignee: Shohei Okumiya
> Priority: Major
> Fix For: 0.10.5
>
> Time Spent: 1h 50m
> Remaining Estimate: 0h
>
> TEZ-4344 added a capability to periodically dump thread information to Tez. I
> think the basic architecture, injecting an additional process into
> DAGAppMaster or TezChild, is potentially extensible.
>
> For example, we maintain a very similar patch to collect stack traces.

> * [https://api-docs.treasuredata.com/blog/hive-distributed-profiling/]
>
> I would propose to make the injection step pluggable and maintain
> TezThreadDumpHelper as one of the plugins.
