Full Description

elasticsearch with kibana accessible from any IP

docker run -d -p 9200:9200 -p 5601:5601 shantanuo/elasticsearch

Make sure that you have allocated enough disk for containers

Check the Data Space Total and if it is default 107.4 GB then increase it by editing config file

docker info | grep Space

Modify the options line and add

vi /etc/sysconfig/docker

-g /var/lib/docker --storage-opt dm.basesize=700G --storage-driver=devicemapper

rm -rf /var/lib/docker/

mkdir -p /var/lib/docker/devicemapper/devicemapper

dd if=/dev/zero of=/var/lib/docker/devicemapper/devicemapper/data bs=1G count=0 seek=250

disable replication and limit number of shards

curl -XPUT 'localhost:9200/enwiki_content' -d '
"settings": {
"index" : {
"number_of_shards" : 1,
"number_of_replicas" : 0

Download wikipedia data

test with 50 MB JSON file

time wget

time gunzip emlwiki-20160502-cirrussearch-content.json.gz

time curl -s -XPOST localhost:9200/wikipedia_content/somelan/_bulk --data-binary @emlwiki-20160502-cirrussearch-content.json

This is 31 GB compressed english wikipedia


time gunzip enwiki-20160502-cirrussearch-general.json.gz

time curl -s -XPOST localhost:9200/wikipedia_content/somelan/_bulk --data-binary @enwiki-20160502-cirrussearch-general.json

Or use parallel for faster load

time zcat enwiki-20160502-cirrussearch-general.json.gz | parallel --pipe -L 2 -N 2000 -j3 'curl -s http://localhost:9200/enwiki_content/_bulk --data-binary @- > /dev/null'

It will take around 24 hours to load more than 2 Crore records (2,52,46,582)

Connect to ES

Check the indexes

curl 'localhost:9200/_cat/indices?v'

python code to connect

import elasticsearch

es = elasticsearch.Elasticsearch('')

res ="wikipedia_content", body={"query": {"match_all": {}}})

print("Got %d Hits:" % res['hits']['total'])
