knapsack question - Githubissues

jprante commented 11 years ago

I installed knapsack on elasticsearch v0.90.1 successfully.

I tried to export an index named g4 per the README instructions. My command and return value is as follows:

curl -XPOST "http://localhost:9200/g4/file/_export" {"error":"MapperParsingException[failed to parse, document is empty]","status":400}

As you can see the result was an error. Am I supposed to be using curl's -d option to pass in a JSON document, or should this have successfully exported?

I'm getting the same :( Did you manage to solve it? Thanks

clintonb commented 11 years ago

I am having the same issue on 0.90.5. I followed the example exactly:

[cblackburn@dev-search ~]$ curl -XPUT localhost:9200/test/test/1 -d '{"key":"value 1"}'
{"ok":true,"_index":"test","_type":"test","_id":"1","_version":1}

[cblackburn@dev-search ~]$ curl -XPUT localhost:9200/test/test/2 -d '{"key":"value 2"}'
{"ok":true,"_index":"test","_type":"test","_id":"2","_version":1}

[cblackburn@dev-search ~]$ curl -XPOST localhost:9200/test/test/_export
{"error":"MapperParsingException[failed to parse, document is empty]","status":400}

Just released 2.1.0 with a fix, can you check if the issue still persists?

clintonb commented 11 years ago

Upgrading did not work.

jprante commented 11 years ago

Did you restart the node? Each plugin install needs a restart.

clintonb commented 11 years ago

Yes, I tried restarting. No change.

clintonb commented 10 years ago

I was able to resolve this issue. It turned out my heap size settings were wrong, leading to the plugin not being loaded.
