Shane Kumpf commented on YARN-6830: ----------------------------------- [~templedf] - hoping you might have time to take another look. thanks in advance. > Support quoted strings for environment variables > ------------------------------------------------ > > Key: YARN-6830 > URL: https://issues.apache.org/jira/browse/YARN-6830 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Shane Kumpf > Assignee: Shane Kumpf > Attachments: YARN-6830.001.patch > > > There are cases where it is necessary to allow for quoted string literals > within environment variables values when passed via the yarn command line > interface. > For example, consider the follow environment variables for a MR map task. > {{MODE=bar}} > {{IMAGE_NAME=foo}} > {{MOUNTS=/tmp/foo,/tmp/bar}} > When running the MR job, these environment variables are supplied as a comma > delimited string. > {{-Dmapreduce.map.env="MODE=bar,IMAGE_NAME=foo,MOUNTS=/tmp/foo,/tmp/bar"}} > In this case, {{MOUNTS}} will be parsed and added to the task environment as > {{MOUNTS=/tmp/foo}}. Any attempts to quote the embedded comma separated value > results in quote characters becoming part of the value, and parsing still > breaks down at the comma. > This issue is to allow for quoting the comma separated value (escaped double > or single quote). This was mentioned on YARN-4595 and will impact YARN-5534 > as well. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
