Hi @aditya-agrawal, we have found your signature in our records, but it seems like you have signed with a different e-mail than the one used in yout Git commit. Can you please add both of these e-mails into your Github profile (they can be hidden), so we can match your e-mails to your Github profile? |
Done. |
@karmi can you please review the PR and let me know if I need to change anything? |

Hi @aditya-agrawal, thanks for opening this PR. In order to get this merged, we would need at least some unit tests that show that this fixes the reported issue. I'm not sure if TermVectorsWriter#setFields can be tested individually, for the NPE this might be possible.
For the whole two fields scenario described in the issue it probably makes sense to add something similar to MoreLikeThisIT, although a unit test would be prefered as well if possible.
Okay @cbuescher I am working on it. |
@cbuescher I have written the integration test for the two field scenario given in the ticket. |

Thanks for the test, LGTM. I left one super tiny nit-pick, nothing to really worry about. I will kick of a full CI test run to see if anything else turns up.
Could you add a line mentioning this PRs title and number similar to e.g. https://github.com/elastic/elasticsearch/pull/29641/files#diff-297418c07078d2b31d8e94a7d34b5255 to the docs/CHANGELOG.asciidoc. I think this fix should also be backported to the next 6.x branches. At the moment I believe this means putting the same entry in two places (under 7.0 and 6.4). I will edit the title slightly so make it a bit shorter. Thanks a lot.

nit: could you remove the second empty line (or maybe even both?), I think a few empty lines to separate blocks don't hurt but too many are also just bloating the code.

@elasticmachine test this please |
@cbuescher I have made the suggested changes. |
@elasticmachine test this please |
Fixes and edge case when using `more_like_this` where TermVectorsWriter could throw an NPE when a field produced zero tokens after analysis. This changes the implementation to use an empty list of tokens in this case. Closes #30148
@aditya-agrawal thanks a lot, merged to master and the upcoming 6.4 branch. |

At this point ->
https://github.com/elastic/elasticsearch/blob/master/server/src/main/java/org/elasticsearch/action/termvectors/TermVectorsWriter.java#L69
fieldTermVector is getting null in case of empty field. I initialized fieldTermVector with EMPTY_TERMS in case of null. This solves both the given issue given in the ticket.
