Juan Yu created HDFS-6493:
-----------------------------
Summary: Propose to 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
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?
