Review request for Ambari, Jaimin Jetly and Yusaku Sako.
Bugs: AMBARI-9279
https://issues.apache.org/jira/browse/AMBARI-9279
Repository: ambari
Description
-------
After enabling Kerberos MapReduce2 Service Check failed with issue writing to
local file system. This fix attempts to set the ACLs on the relevant
directories to solve this issue:
Before Kerberos
```
drwxrwxr-x 5 yarn hadoop 4096 Jan 22 00:01 /hadoop/yarn/local
drwxr-xr-x 3 yarn hadoop 4096 Jan 22 00:00 /hadoop/yarn/local/usercache
drwxr-x--- 4 yarn hadoop 4096 Jan 22 00:00
/hadoop/yarn/local/usercache/ambari-qa
drwx--x--- 2 yarn hadoop 4096 Jan 22 00:01
/hadoop/yarn/local/usercache/ambari-qa/appcache
```
After Kerberos:
```
drwxrwxr-x 5 yarn hadoop 4096 Jan 22 01:23 /hadoop/yarn/local
drwxr-xr-x 3 yarn hadoop 4096 Jan 22 00:00 /hadoop/yarn/local/usercache
drwxr-s--- 4 ambari-qa hadoop 4096 Jan 22 00:00
/hadoop/yarn/local/usercache/ambari-qa
drwx--x--- 2 yarn hadoop 4096 Jan 22 00:01
/hadoop/yarn/local/usercache/ambari-qa/appcache
```
This fix updates `/hadoop/yarn/local/usercache/ambari-qa/appcache` from
```
drwx--x--- 2 yarn hadoop 4096 Jan 22 00:01
/hadoop/yarn/local/usercache/ambari-qa/appcache
```
to
```
drwx--x--- 2 ambari-qa hadoop 4096 Jan 22 00:01
/hadoop/yarn/local/usercache/ambari-qa/appcache
```
