Rajesh Balamohan commented on TEZ-3802:
---------------------------------------
Hive in LLAP has its own shuffle handler. HIVE-16740 is on similar lines i
believe.
> Tez Shuffle Handler TezSpillRecord Cache hit rate is very low

> URL: https://issues.apache.org/jira/browse/TEZ-3802
> Project: Apache Tez
> Issue Type: Bug
> Reporter: Jonathan Eagles
>
> TezSpillRecord Cache assumes that mapId query param is equal the the map
> attempt name. But it is actually has the spill record index
> attempt_1500002415313_1170497_1_00_026491_0_10023
> pathCache needs to be investigate to understand if it's affected as well.
