Key: AMBARI-13517
URL: https://issues.apache.org/jira/browse/AMBARI-13517
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.1.2
Reporter: Siddharth Wagle
Assignee: Siddharth Wagle
Priority: Critical
Fix For: 2.1.3
Max Heap restriction problem: Ehcache library that we use has a limit of how
far in the object graph it traverses to find size of an Cached reference, this
is to make it performant. Default limit = 1000.
_Objective of the patch_:
- Provide a custom Sizing engine for Ehcache that will provide a close
approximation of the data in the cache with significant perf gain. Premise:
Since we know the data structures we can make better estimates.
- Expectation from sizing engine : Discrepancy of less than 10K for a DS of
size 10 MB (Proven with a unit test)
