navis requested code review of "HIVE-4709 [jira] Caching OIs in OIFactory
should be disabled".
Reviewers: JIRA
HIVE-4709 Caching OIs in OIFactory should be disabled
OIFactory has various caches and most of them are accessed by key containing
OIs. But OIs are not forced to implement hashCode/equals and that is resulted
to some kind of memory leakage.
Considering the price of calculating/accessing hashmap, just removing those
caches are better solution, IMHO.
