Steve Loughran commented on HADOOP-15302: ----------------------------------------- Based on similar self-loading stuff, what happens when there's a failure to load? What diagnostics gets printed, and can it be tied back to a specific service confg? > Enable DataNode/NameNode service plugins with Service Provider interface > ------------------------------------------------------------------------ > > Key: HADOOP-15302 > URL: https://issues.apache.org/jira/browse/HADOOP-15302 > Project: Hadoop Common > Issue Type: Improvement > Reporter: Elek, Marton > Assignee: Elek, Marton > Priority: Major > Attachments: HADOOP-15302.001.patch > > > HADOOP-5257 introduced ServicePlugin capabilities for NameNode/DataNode. As > of now they could be activated by configuration values. > I propose to activate plugins with Service Provider Interface. In case of a > special service file is added a jar it would be enough to add the plugin to > the classpath. It would help to add optional components to NameNode/DataNode > with settings the classpath. > This is the same api which could be used in java 9 to consume defined > services. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
