I have changed the permission of my directory and have given write access for that user.

Answer 1

Most likely you forgot to set the root directory for indexes, and Hibernate Search defaults to storing indexes in the JVM's working directory (whatever it is).
Set the property hibernate.search.default.indexBase to a directory you know the application will have write access to, and this should go away. See https://docs.jboss.org/hibernate/search/5.11/reference/en-US/html_single/#search-configuration-directory for more information about configuring the directories.
Regarding the fact that it worked the first time... I would assume something was different the first time. Maybe Hibernate Search was disabled, or you started the application from another directory? Anyway, the real problem is most likely related to access rights.
