Subject [jira] [Commented] (BIGTOP-479) init.d scripts should provide an option for initializing persistent state of the services that require it
Date Thu, 22 Mar 2012 17:04:22 GMT

    [ https://issues.apache.org/jira/browse/BIGTOP-479?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13235726#comment-13235726
] 

James Page commented on BIGTOP-479:
-----------------------------------

I think having helpers that do this is useful - but I don't think the init script is the correct
place todo this.

Rationale: if users want to use upstart or systemd in the future we don't really have the
option to have an extra command for 'init' as they work in a different way.

> The following services require an explicit initialization of the persistent state in
the local filesystem:
>    # Hadoop NameNode (formatting a namenode via: hdfs namenode -format)
>    # ZooKeeper (formatting a local storage area via: zookeeper-server-initialize)
> and the following ones require an initialization of the RDBMS database (which can reside
on a local filesystem
> via Derby or be hosted on a remote server such as Postgress, MySQL, Oracle, etc.):
>    # oozie DB (initialized via ooziedb.sh)
>    # possible Hive metastore
>    # possibly Sqoop metastore
> In order to free the user from an explicit knowledge of what command to run under which
account it is desirable
> to have an init.d scripts for the above components support and extra command called 'init'.
> Please let me know what do you all think.
