NPE in ContextIndexSearcher

Elastic Stack Elasticsearch
1

Hi,

I'm using the ElasticSearch FrontEnd client ( https://github.com/mobz/elasticsearch-head ). The last version in master...

I use it with ES 0.16.1.

When I try to search (simple match_all query), I get a NPE.

Here is what ESFrontEnd is sending to ES :
{
query: {
bool: {
must: [
{
match_all: { }
}
]
must_not: [ ]
should: [ ]
}
}
from: 0
size: 50
sort: [ ]
facets: { }
}

In ES logs, I get :
[2011-05-17 09:08:40,592][DEBUG][action.search.type ] [The Entity] [dau][4], node[6bzzlBiuTVu52IhXYwE4Qw], [P], s[STARTED]: Failed to execute [org.elasticsearch.action.search.SearchRequest@1b6ba28]
java.lang.NullPointerException

at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)
at java.lang.Thread.run(Thread.java:619)

It seems that there is a NPE in ContextIndexSearcher.removeCollectors().
Something strange is that I'm not in DEBUG mode. I use the standard logging setup file but the trace seems to be a DEBUG trace...

Thanks for any help.
Should I open a bug for that ?

Cheers

Heya,

Yea, this looks like a possible bug when providing empty facets element. Opened an issue for it: Search: Empty facets element causes search failures · Issue #938 · elastic/elasticsearch · GitHub.
