[jira] Resolved: (HBASE-1976) HBaseConfiguration implements hashCode() without implementing equals()

     [ https://issues.apache.org/jira/browse/HBASE-1976?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack resolved HBASE-1976.
--------------------------

    Fix Version/s: 0.90.0
       Resolution: Invalid

Resolving invalid.  HBaseConfiguration had an equals added a good while ago which is what this issue is about.  Adding equals and a hashcode in the first place was probably a mistake.  Will likely be backed out by hbase-2925, but regardless, this issue was 'addressed' a while back.  Closing.  Thanks for filing Age.

> I was browsing though the HBase 0.20.1 code in order to learn about the way HBase deals with Configuration and I noticed that HBaseConfiguration overrides hashCode() without implementing equals(). This can cause some tricky, hard to debug problems whenever instances of this class are added to Maps or HashSets.
