Elek, Marton created HADOOP-15656: ------------------------------------- Summary: Support byteman in hadoop-runner baseimage Key: HADOOP-15656 URL: https://issues.apache.org/jira/browse/HADOOP-15656 Project: Hadoop Common Issue Type: Improvement Reporter: Elek, Marton Assignee: Elek, Marton
[Byteman|http://byteman.jboss.org/] is an easy to use tool to instrument a java process with agent string. For example [this script|https://gist.githubusercontent.com/elek/0589a91b4d55afb228279f6c4f04a525/raw/8bb4e03de7397c8a9d9bb74a5ec80028b42575c4/hadoop.btm] defines a rule to print out all the hadoop rpc traffic to the standard output (which is extremely useful for testing development). This patch adds the byteman.jar to the baseimage and defines a simple logic to add agent instrumentation string to the HADOOP_OPTS (optional it also could download the byteman script from an url) -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
