Dinesh Chitlangia commented on HDDS-1581: ----------------------------------------- [~xyao] Thanks. I will log a patch shortly. > Atleast one of the metadata dir config property must be tagged as REQUIRED > -------------------------------------------------------------------------- > > Key: HDDS-1581 > URL: https://issues.apache.org/jira/browse/HDDS-1581 > Project: Hadoop Distributed Data Store > Issue Type: Bug > Affects Versions: 0.4.0 > Reporter: Dinesh Chitlangia > Assignee: Dinesh Chitlangia > Priority: Major > Labels: configuration > > This issue was discovered while working on HDDS-373 to generate a minimal > ozone-site.xml with required values. > {panel:title=ozone-default.xml} > <property> > <name>ozone.metadata.dirs</name> > <value/> > <tag>OZONE, OM, SCM, CONTAINER, STORAGE</tag> > <description> > This setting is the fallback location for SCM, OM and DataNodes > to store their metadata. This setting may be used in test/PoC clusters > to simplify configuration. > For production clusters or any time you care about performance, it is > recommended that ozone.om.db.dirs, ozone.scm.db.dirs and > dfs.container.ratis.datanode.storage.dir be configured separately. > </description> > </property> > {panel} > However, none of the properties listed above are tagged as REQUIRED. > For starters, as the goal of HDDS-373 is to generate a simple minimal > ozone-site.xml that can be used to start ozone, I propose that we do either > of the following: > 1. Tag ozone.metadata.dirs as REQUIRED > OR > 2. Tag ozone.om.db.dirs, ozone.scm.db.dirs and > dfs.container.ratis.datanode.storage.dir as REQUIRED > For simplicity, I would prefer option 1 as that is the fallback config. We > have already stated that for production use, we must defined the granular > properties instead of relying on this fallback property ozone.metadata.dirs > cc: [~anu], [~arp], [~ajayydv] could you share your 2 cents pls? :) -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
