Subject [jira] [Commented] (HBASE-6833) [WINDOWS] Java Milisecond precision on Windows
Date Mon, 24 Sep 2012 21:20:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6833?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13462152#comment-13462152

Lars Hofhansl commented on HBASE-6833:

@Ram: HBASE-6784. That's a badly written test. I wrote it :)  I will fix it. No test should
make any (implicit or explicit assumptions about the progression of time).

> HBase relies on the system clock obtained by System.currentTimeMilis() to supply the
version, if it is not provided by the client in Put's and Delete's. At HBASE-6832 and HBASE-6826,
we discovered that on some platforms, the milis clock might not be updated every milisecond,
which might cause unexpected behavior. We also did some preliminary analysis there.
> In this issue, we can further discuss and inspect whether it is a problem for main target
platforms and if so what can be done.
