UnavailableShardsException - mysql

Question

I want to index and search mysql database using elasticsearch & I followed this tutorial
https://github.com/jprante/elasticsearch-river-jdbc/wiki/Quickstart
At first I downloaded elasticsearch and installed river-jdbc in its plugin folder. then added mysql-jdbc inside ES_HOME/plugins/river-jdbc/ Then started elasticsearch and Started another terminal window, and created a new JDBC river with name my_jdbc_river with this curl command
curl -XPUT 'localhost:9200/_river/my_jdbc_river/_meta' -d '{
"type" : "jdbc",
"jdbc" : {
"driver" : "com.mysql.jdbc.Driver",
"url" : "jdbc:mysql://localhost:3306/bablool",
"user" : "root",
"password" : "babloo",
"sql" : "select * from details"
},
"index" : {
"index" : "jdbc",
"type" : "jdbc"
}
}'
I'm getting the following error:-
then when I run this command: curl -XGET 'localhost:9200/jdbc/jdbc/_search?pretty&q=*'
and I'm getting following error:
"error": "IndexMissingException[[jdbc] missing]", "status" : 404
And when I give this in my browser:
http://localhost:9201/_search?q=*
Im getting like this:
{
"took": 51,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 1.0,
"hits": [
{
"_index": "_river",
"_type": "my_jdbc_river",
"_id": "_meta",
"_score": 1.0,
"_source": {
"type": "jdbc",
"jdbc": {
"driver": "com.mysql.jdbc.Driver",
"url": "jdbc:mysql://localhost:3306/bablool",
"user": "root",
"password": "babloo",
"sql": "select * from details"
},
"index": {
"index": "jdbc",
"type": "jdbc"
}
}
}
]
}
}
Is mysql dB indexed? How can I Search in my Db?

Answer 1

I encountered similar problem and this is how I managed to solve the issue:
Firstly, I checked all the indices via http://localhost:9200/_cat/indices?v
Deleted all indices with health status as red (there was just one index _river with health status red)
This is how you delete in index curl -XDELETE 'localhost:9200/_river/'
Redo step 7 in link you mentioned https://github.com/jprante/elasticsearch-river-jdbc/wiki/Quickstart
Hope it solves your problem as well :) Good luck!!
