Cannot start elasticsearch when change language file

[Bongsakorn]

I changed some language file in resources/langdetect path. Then re-build and install into ES. so ES cannot start properly, there are many error about shard on it.

I tried it on my local ES but not found like this.

I guess, Is it possible, Index already save language frequency resource in to the index then I change resource file, it's not replace them into the index.

What's wrong with it? Anyone could give me suggestion?
