ElasticSearch throwing mapper parsing exception when indexing JSON array of integers and strings
<p>I am attempting to use python to pull a JSON array from a file and input it into ElasticSearch. The array looks as follows:</p>

<pre><code>{"name": [["string1", 1, "string2"],["string3", 2, "string4"], ... (variable length) ... ["string n-1", 3, "string n"]]}
</code></pre>

<p>ElasticSearch throws a TransportError(400, mapper_parsing_exception, failed to parse) when attempting to index the array. I discovered that ElasticSearch sometimes throws the same error whenever I try to feed it a string with both strings and integers. So, for example, the following will sometimes crash and sometimes succeed:</p>

<pre><code>import json
from elasticsearch import Elasticsearch

es = Elasticsearch()

test = json.loads('{"test": ["a", 1, "b"]}')
print test
es.index(index, body=test)
</code></pre>

<p>This code is everything I could safely comment out without breaking the program. I put the JSON in the program instead of having it read from a file. The actual strings I'm inputting are quite long (or else I would just post them) and will always crash the program. Changing the JSON to "test": ["a"] will cause it to work. The current setup crashes if it last crashed, or works if it last worked. What is going on? Will some sort of mapping setup fix this? I haven't figured out how to set a map with variable array length. I'd prefer to take advantage of the schema-less input but I'll take whatever works.</p>
