ASF GitHub Bot commented on FLINK-8247: --------------------------------------- jaredstehler commented on issue #6689: [FLINK-8247] [Mesos] Support case where hadoop is not on classpath URL: https://github.com/apache/flink/pull/6689#issuecomment-422062032 @EronWright Yeah, I was going for the least invasive change. With regard to the classloading issue: I was surprised as well; I think we don't trip on the missing class until it's initially used in the static context: `UserGroupInformation.getCurrentUser();`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.

The Mesos job manager > normally uses the Hadoop UserGroupInformation class to overlay a user context > (`HADOOP_USER_NAME`) for the task managers. > Detect the absence of Hadoop and skip over the `HadoopUserOverlay`, similar > to the logic in `HadoopModuleFactory`. This may require the introduction > of an overlay factory. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
