[jira] [Updated] (TEZ-1879) Create local UGI instances for each task and the AM, when running in LocalMode

["Siddharth Seth (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TEZ-1879?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Siddharth Seth updated TEZ-1879:
--------------------------------
    Attachment: TEZ-1879.1.txt

Fairly straighforward patch which requires Credentials to be moved around. UGI for the AM and Child are already being created explicitly, so didn't need to do much there. No new unit tests since this functionality is covered by the existing local mode and MiniCluster tests.

[~hitesh] - please review.

> Modifying the client UGI can cause issues when the client tries to submit another job - or has tokens already populated in the UGI.
