Subject [jira] [Commented] (HDFS-9847) HDFS configuration without time unit name should accept friendly time units
Date Thu, 24 Mar 2016 16:27:25 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9847?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15210501#comment-15210501
] 

Chris Douglas commented on HDFS-9847:
-------------------------------------

bq. Remove the warning on line 1651 in Configuration.java. Else I think this change will introduce
warnings for all existing deployments.

This is the WARN for missing units? It should warn, shouldn't it? The calls specifying TimeUnit.SECONDS
are for backwards compatibility, and would otherwise be in millis. The changes to {{hdfs-default.xml}}
should include units (changing their type) in this release, then we can change the caller
after users have been warned for using values without units.

> In HDFS-9821, it talks about the issue of leting existing keys use friendly units e.g.
60s, 5m, 1d, 6w etc. But there are som configuration key names contain time unit name, like
{{dfs.blockreport.intervalMsec}}, so we can make some other configurations which without time
unit name to accept friendly time units. The time unit  {{seconds}} is frequently used in
hdfs. We can updating this configurations first.
