我正在尝试从JSON文件(其中每行包含一个文档)将数据导入Elasticsearch。仅数据。
这是我创建索引并尝试插入一个文档的方式:
DELETE /tests
PUT /tests
{}
PUT /tests/test/_mapping
{
"test":{
"properties":{
"env":{"type":"keyword"},
"uid":{"type":"keyword"},
"ok":{"type":"boolean"}
}
}
}
POST /tests/test
{"env":"dev", "uid":12346, "ok":true}
GET /tests/_search
{"query":{"match_all":{}}}
一切正常,没有错误,文档已正确索引并且可以在ES中找到。
现在让我们尝试使用elasticdump
来做到这一点。
这是我要导入的文件的内容:
cat ./data.json
{"env":"prod","uid":1111,"ok":true}
{"env":"prod","uid":2222,"ok":true}
这是我要导入的方式:
elasticdump \
--input="./data.json" \
--output="http://elk:9200" \
--output-index="tests/test" \
--debug \
--limit=10000 \
--headers='{"Content-Type": "application/json"}' \
--type=data
但是我遇到了错误Compressor detection can only be called on some xcontent bytes or compressed xcontent bytes
。
此处为完整输出:
root@node-tools:/data# elasticdump \
> --input="./s.json" \
> --output="http://elk:9200" \
> --output-index="tests/test" \
> --debug \
> --limit=10000 \
> --headers='{"Content-Type": "application/json"}' \
> --type=data

我在做什么错?为什么在_batch
抛出错误时手动插入可以正常工作。有什么想法吗?
UPD
尝试使用python的elasticsearch_loader
-正常工作。
elasticsearch_loader \
--es-host="http://elk:9200" \
--index="tests" \
--type="test" \
json --json-lines ./data.json

答案 0 :(得分:1)
Json文档应以_source
的形式提供。
WAS:{"env":"prod","uid":1111,"ok":true}
现在:{"_source":{"env":"prod","uid":1111,"ok":true}}
elasticdump
可以使用--transform
自变量来实现:
elasticdump \
--input="./data.json" \
--output="http://elk:9200" \
--output-index="tests/test" \
--debug \
--limit=10000 \
--type=data \
--transform="doc._source=Object.assign({},doc)"
