Cannot notify file changes listener

Hi
i have elasticsearch 5.2
i'm trying to update the /etc/elasticsearch/x-pack/role_mapping.yml file

when i do that i get the following Warning:

[2017-03-16T16:36:51,535][INFO ][o.e.x.s.a.s.DnRoleMapper ] [elasticsearch_node] role mappings file [/etc/elasticsearch/x-pack/role_mapping.yml] changed for realm [active_directory/active_directory]. updating mappings...
[2017-03-16T16:36:51,537][WARN ][o.e.w.FileWatcher        ] cannot notify file changes listener
java.lang.NullPointerException: null

What is the problem?

Can you post the role_mapping.yml file? Maybe there is a format error.

Sorry that we missed this question when it was posted.

This is related to a bug in 5.2, that has been fixed in 5.3.
It's relatively harmless, but it's a good idea to upgrade if you can.
