>             Project: Hive
>          Issue Type: Improvement
>            Reporter: László Bodor
>            Priority: Major

> Hive has a copy of IndexCache class:
> hive: https://github.com/apache/hive/blob/master/llap-server/src/java/org/apache/hadoop/hive/llap/shufflehandler/IndexCache.java
> tez: https://github.com/apache/tez/blob/master/tez-plugins/tez-aux-services/src/main/java/org/apache/tez/auxservices/IndexCache.java
> As far as I can see, the Hive version doesn't add any value into it (compared by eyes so far) and maintaining is extra effort, for instance:
> HIVE-23029 copied improvements of TEZ-3887 which is almost 2 years old
> HIVE-23190 is blocked on a tez release which contains TEZ-4145
