Subject [jira] [Commented] (HBASE-6476) Replace all occurrances of System.currentTimeMillis() with EnvironmentEdge equivalent
Date Thu, 06 Sep 2012 04:40:09 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6476?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13449410#comment-13449410
] 

Ted Yu commented on HBASE-6476:
-------------------------------

>From N:
bq. I've done it just before this patch after a comment from Stack, but after some thinking
I don't think it's a good idea: in tests you want the real time.

> There are still some areas where System.currentTimeMillis() is used in HBase. In order
to make all parts of the code base testable and (potentially) to be able to configure HBase's
notion of time, this should be generally be replaced with EnvironmentEdgeManager.currentTimeMillis().
> How hard would it be to add a maven task that checks for that, so we do not introduce
System.currentTimeMillis back in the future?
