[jira] [Commented] (BEAM-8278) Get output from PROCESS environment

    [ https://issues.apache.org/jira/browse/BEAM-8278?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16932836#comment-16932836 ] 

Kyle Weaver commented on BEAM-8278:
-----------------------------------

It is actually possible to see the output of the process, it's just not enabled by default. If the Flink logger is set to DEBUG, the process output will be sent to the stdout of the task manager.
