Subject [jira] Commented: (HADOOP-3486) No config parameter for initial block report detail sin Hadoop-defaults.xml
Date Tue, 03 Jun 2008 20:44:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3486?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12602065#action_12602065
] 

Owen O'Malley commented on HADOOP-3486:
---------------------------------------

There is a reasonable case to be made for setting this to 0 secs in the default.

In particular, now hdfs on a single node configuration takes much much longer to come up than
before.

> HADOOP-2326 added a new config parameter for the initial block report that gets sent
after DataNode registration but this config parameter was not documented in the Hadoop-defaults.xml
> This Jira fixes that.
>  - conf/hadoop-defaults.xml uses a default value of 60 sec (as does the code)
>   - src/test/haddoop-sites uses a default value of 0 sec.
