> Key: YARN-3514
> URL: https://issues.apache.org/jira/browse/YARN-3514
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 2.2.0
> Environment: CentOS6
> Reporter: john lilley
> Priority: Minor
> Labels: oct16-easy
> Attachments: YARN-3514.001.patch, YARN-3514.002.patch

> We have a 2.2.0 (Cloudera 5.3) cluster running on CentOS6 that is
> Kerberos-enabled and uses an external AD domain controller for the KDC. We
> are able to authenticate, browse HDFS, etc. However, YARN fails during
> localization because it seems to get confused by the presence of a \
> character in the local user name.
> Our AD authentication on the nodes goes through sssd and set configured to
> map AD users onto the form domain\username. For example, our test user has a
> Kerberos principal of hadoopu...@domain.com and that maps onto a CentOS user
> "domain\hadoopuser". We have no problem validating that user with PAM,
> logging in as that user, su-ing to that user, etc.
> However, when we attempt to run a YARN application master, the localization
> step fails when setting up the local cache directory for the AM. The error
> that comes out of the RM logs:
> 2015-04-17 12:47:09 INFO net.redpoint.yarnapp.Client[0]: monitorApplication:
> ApplicationReport: appId=1, state=FAILED, progress=0.0, finalStatus=FAILED,
> diagnostics='Application application_1429295486450_0001 failed 1 times due to

> -1000 due to: Application application_1429295486450_0001 initialization

> .Failing this attempt.. Failing the application.'
> However, when we look on the node launching the AM, we see this:
> [root@rpb-cdh-kerb-2 ~]# cd /data/yarn/nm/usercache
> [root@rpb-cdh-kerb-2 usercache]# ls -l
> drwxr-s--- 4 DOMAIN\hadoopuser yarn 4096 Apr 17 12:10 domain\hadoopuser
> There appears to be different treatment of the \ character in different
> places. Something creates the directory as "domain\hadoopuser" but something
> else later attempts to use it as "domain%5Chadoopuser". I’m not sure where
> or why the URL escapement converts the \ to %5C or why this is not consistent.
> I should also mention, for the sake of completeness, our auth_to_local rule
> is set up to map u...@domain.com to domain\user:
> RULE:[1:$1@$0](^.*@DOMAIN\.COM$)s/^(.*)@DOMAIN\.COM$/domain\\$1/g
