-----------------------------------
Summary: Remove unnecessary contention on locks by getDag,
getTask, getVertex etc
Key: TEZ-2288
URL: https://issues.apache.org/jira/browse/TEZ-2288
Project: Apache Tez
Issue Type: Improvement
Reporter: Siddharth Seth
There's a lot of unnecessary contention on the dag lock when trying to find a
task or vertex. Likewise, there's likely contention on Vertex locks. A lot of
this is avoidable. One simple fix would be to make the dag / vertex etc
available in Tasks.
appContext.getCurrentDag doesn't seem to be thread safe either.
