[jira] [Commented] (HADOOP-13440) FileContext does not react on
changing umask via configuration
[ https://issues.apache.org/jira/browse/HADOOP-13440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15588160#comment-15588160 ]
Tao Yang commented on HADOOP-13440:
-----------------------------------
Hi [~ajisakaa]. There is a problem in YARN-5749 occurred by this solution. FileContext is used with different umask value in Multiple services use FileContext objects with different umask, therefor they may affect each other through changing umask in some scenarios. Could you give some suggestions to solve this problem? Thank you.
