> Change dfs.namenode.startup.delay.block.deletion to second instead of
> millisecond
> ---------------------------------------------------------------------------------
>
> Key: HDFS-6493
> URL: https://issues.apache.org/jira/browse/HDFS-6493
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Juan Yu
> Assignee: Juan Yu
> Priority: Trivial
> Fix For: 2.5.0
>
> Attachments: HDFS-6493.001.patch
>
>
> Based on the discussion in https://issues.apache.org/jira/browse/HDFS-6186,
> the delay will be at least 30 minutes or even hours. it's not very user
> friendly to use milliseconds when it's likely measured in hours.
> I suggest to make the following change
> 1. change the unit of this config to second
> 2. rename the config key from "dfs.namenode.startup.delay.block.deletion.ms"
> to "dfs.namenode.startup.delay.block.deletion.sec"
> 3. add the default value to hdfs-default.xml, what's the reasonable value, 30
> minutes, one hour?
