Hibernate Search on EC2, "Unable to create index directory"

I'm trying to implement Hibernate Search on my aws application. As usual, everything works great on localhost, but when upload to aws, I receive the following error:

org.hibernate.search.SearchException: Unable to create index directory: 
/usr/lucene/indexes for index com.myproject.domain.User

My Hibernate Search config:

<prop key="hibernate.search.default.directory_provider">filesystem</prop>
<prop key="hibernate.search.default.indexBase">/usr/lucene/indexes</prop>

I'm using EC2 + elastic beanstalk, linux with tomcat 7. I have windows on my local machine.

Should I create a directory named "/usr/lucene/indexes" on EC2 manually? Thanks.
