Hi,
In the index template, I forgot to define the index.lifecycle.rollover_alias and triggered the following error:
Index lifecycle error
illegal_argument_exception: setting [index.lifecycle.rollover_alias] for index [xxxxx-index] is empty or not defined
I just updated the index template with providing the rollover_alias.
I would like to ask how to fix the created index with the missing "rollover_alias".
Thanks.
