Subject [jira] [Commented] (HBASE-6476) Replace all occurrances of System.currentTimeMillis() with EnvironmentEdge equivalent
Date Thu, 06 Sep 2012 21:30:08 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6476?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13450063#comment-13450063
] 

Chris Trezzo commented on HBASE-6476:
-------------------------------------

How about as an intermediate step we do the following:

1. Change all the occurrences in src/main code (that way when a new test uses EnvEdge they
get predictable behaviour).
2. Add a check to hadoopQA to ensure no new occurrences are added.

In the future, people can change the occurrences in test code on an as-needed test-by-test
basis.

Thoughts?

If this sounds good, I can post a re-based version and a HadoopQA check.

> 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?
