Steve Loughran commented on HADOOP-13628: ----------------------------------------- Here's why I'd like the text option: you can feed the entire value into something, like a curl > file without doing any JSON parsing. all that's needed it to look at the type: text/plain = text, text/json ==json, etc. It's the RESTy way. > Support to retrieve specific property from configuration via REST API > --------------------------------------------------------------------- > > Key: HADOOP-13628 > URL: https://issues.apache.org/jira/browse/HADOOP-13628 > Project: Hadoop Common > Issue Type: Improvement > Components: conf > Affects Versions: 2.7.3 > Reporter: Weiwei Yang > Assignee: Weiwei Yang > Attachments: HADOOP-13628.01.patch, HADOOP-13628.02.patch > > > Currently we can use rest API to retrieve all configuration properties per > daemon, but unable to get a specific property by name. This causes extra > parse work at client side when dealing with Hadoop configurations, and also > it's quite over head to send all configuration in a http response over > network. Propose to support following a {{name}} parameter in the http > request, by issuing > {code} > curl --header "Accept:application/json" > http://${RM_HOST}/conf?name=yarn.nodemanager.aux-services > {code} > get output > {code} > {"property"{"key":"yarn.resourcemanager.hostname","value":"${RM_HOST}","isFinal":false,"resource":"yarn-site.xml"}} > {code} > This change is fully backwards compatible. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
