------------------------------------
Summary: Multipile identical CacheConfig log messages in a log
file and refactoring around CacheConfig inheritance
Key: HBASE-17015
URL: https://issues.apache.org/jira/browse/HBASE-17015
Project: HBase
Issue Type: Improvement
Reporter: Umesh Agashe
Assignee: Umesh Agashe
There are two issues here:
1. CacheConfig is logged multiple times (some times on adjacent lines) in log
file. The reason for this is: {code} LOG.info(this) {code} in CacheConfig
constructor. So when CacheConfig and any derived class is instantiated message
appears multiple times in a log. The message itself doesn't have any context
and look identical. Logging CacheConfig from outside constructor will fix this
issue.
2. During debugging its noticed that CacheConfig is meant for in memory block
cache but is used for different caches (in some cases for non in memory block
caches). This can be improved by refactoring the inheritance of CacheConfig.
