Subject [jira] [Updated] (HIVE-23231) LLAP: Consider removing llap-server IndexCache from Hive codebase
Date Fri, 17 Apr 2020 06:00:11 GMT

     [ https://issues.apache.org/jira/browse/HIVE-23231?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

László Bodor updated HIVE-23231:
--------------------------------
    Description: 
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

(maybe there is some history which I'm not aware of (?))
