[jira] [Commented] (YARN-10382) Non-secure YARN access secure HDFS
[ https://issues.apache.org/jira/browse/YARN-10382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17183273#comment-17183273 ]
bianqi commented on YARN-10382:
-------------------------------
[~aajisaka]
{quote}Everyone who can access to the RM can submit jobs to insecure YARN cluster as HDFS superuser. That way they can access HDFS as superuser.
{quote}
We do not use superuser access HDFS.What you said does not fit our scenario.
> Non-secure YARN access secure HDFS
> ----------------------------------
>
> Key: YARN-10382
> URL: https://issues.apache.org/jira/browse/YARN-10382
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: yarn
> Reporter: bianqi
> Priority: Minor
>
> In our production environment, yarn cannot enable kerberos due to yarn environment problems, but our hdfs is to enable kerberos, and now we need non-secure yarn to access secure hdfs.
> It is known that yarn and hdfs are both safe after security is turned on.
> I hope that after enabling hdfs security, you can use non-secure yarn to access secure hdfs, or use secure yarn to access non-secure hdfs.
