Elek, Marton created HADOOP-15065: ------------------------------------- Summary: Make mapreduce specific GenericOptionsParser arguments optional Key: HADOOP-15065 URL: https://issues.apache.org/jira/browse/HADOOP-15065 Project: Hadoop Common Issue Type: Improvement Reporter: Elek, Marton Priority: Minor
org.apache.hadoop.util.GenericOptionsParser is widely used to use common arguments in all the command line applications. Some of the common arguments are really generic: {code} -D <property=value> define a value for a given property -fs <file:///|hdfs://namenode:port> specify default filesystem URL to use, overrides 'fs.defaultFS' property from configurations. -libjars <jar1,...> specify a comma-separated list of jar files to be included in the classpath {code} But some are mapreduce specific: {code} -jt <local|resourcemanager:port> specify a ResourceManager -archives <archive1,...> specify a comma-separated list of archives to be unarchived on the compute machines {code} In the review of HDFS-12588 it was suggested to remove/turn off the mapreduce specific arguments if they are not required (for example in case of starting namenode or datanode). -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
