Recently we changed the Java JDK library from Oracle to RedHat default OpenJDK. Since this change, whenever I am trying to perform reindexing I am getting the IndexNotFoundException: no such index. Does anyone have any idea what could be the reason or do I need to change anything else in the Elasticsearch? Please find the logs here.
I have looked into the Elasticsearch service and it is running fine. Also checked the indices and they do exist in the backend. Not sure why it is saying that the index was not found.
Any suggestions or ideas will be great. Thanks in advance.
