I have noticed it multiple times that when I try to reindex any of my index (/\_reindex), I see multiple tasks which all try to execute same reindexing operation. These tasks still persist even when the reindexing is essentially over.
I don't know what causes this behaviour and It adds load to my search rate.

Can you provide more details, like showing what these tasks are?

I've seen this mentioned a few times now but never been able to reproduce it and I've spent quite a bit of time on reindex. Most folks seem to have no trouble with reindex and, like I said, I can't make it happen either.
Is there any chance you could create a gist of `curl 'localhost:9200/_tasks/?pretty&detailed=true&actions=*reindex` when this happens again? Does it happen every time you reindex or just sometimes? Do you `_update_by_query` or `_delete_by_query` and, if you do, does this ever happen with them?
