Subject [jira] [Commented] (REEF-1034) Change default value of JobSubmissionDirectoryPrefix and add to YarnClientConfiguration
Date Fri, 11 Dec 2015 20:26:46 GMT

Tobin Baker commented on REEF-1034:

There isn't a standard for this on HDFS that I could find. But `/tmp` seems to be a common
choice and is used by MapReduce by default. So the folder is likely to exist and be writable.

> The default value of the {{NamedParameter}} {{org.apache.reef.runtime.yarn.driver.parameters.JobSubmissionDirectoryPrefix}}
is {{/vol1/tmp}}, a directory that is not even present on most systems. The default value
should be something POSIX-compliant like {{/tmp}}, and this parameter should be added to the
{{ConfigurationModule}} {{YarnClientConfiguration.CONF}}.
