/hdp/apps folder is not getting created while installing HDP2.2 using Ambari 1.7

Hi,

I have set up a HDP 2.2 cluster on AWS EC2 using Ambari 1.7.
The cluster is in Ireland region.
After the successful installation on execution of the command

hadoop fs -ls /

Found 7 items
drwxrwxrwx – yarn hadoop 0 2015-04-21 06:46 /app-logs
drwxr-xr-x – hdfs hdfs 0 2015-04-21 06:48 /apps
drwxr-xr-x – mapred hdfs 0 2015-04-21 06:46 /mapred
drwxr-xr-x – hdfs hdfs 0 2015-04-21 06:46 /mr-history
drwxr-xr-x – hdfs hdfs 0 2015-04-21 06:47 /system
drwxrwxrwx – hdfs hdfs 0 2015-04-21 06:49 /tmp
drwxr-xr-x – hdfs hdfs 0 2015-04-21 06:52 /user

It was found that /hdp/apps was not created.

As a result while running YARN job it throws FileNotFoundException.

Same setup was previously created on Frankfurt region where this directory was created.

Please guide me to overcome this issue.

Thanks

Pratik
