Reindex process not found error

[wuhao000]

when I send a post request like 'http://localhost:9200/law_cloud_v3/cases/_reindex/law_cloud_v5/cases',
I got the following response
{"error":{"root_cause":[{"type":"reindexing_exception","reason":"Reindexing process 40d3df50-5c73-4bcb-9a51-0d6240d18141 is not found."}],"type":"reindexing_exception","reason":"Reindexing process 40d3df50-5c73-4bcb-9a51-0d6240d18141 is not found."},"status":500}
Why?

I have 3 nodes for my elasticsearch cluster and I installed the plugin for every node
use the command 'bin/plugin install org.codelibs/elasticsearch-reindexing/2.1.1'
then I restart the cluster and found plugin info as this:
{
"name": "reindexing",
"version": "2.1.1",
"description": "This plugin copies a new index by reindexing.",
"jvm": true,
"classname": "org.codelibs.elasticsearch.reindex.ReindexingPlugin",
"isolated": true,
"site": false
}
for every node.
then I use the chrome browser send the request
'http://221.231.138.25:9200/law_cloud_v3/_reindex/law_cloud_v4'
I thought should I send the request use the post method？
then I use the java httpclient send a post request with the same url

String url = "http://221.231.138.38:9200/law_cloud_v3/_reindex/law_cloud_v4"; HttpUtil httpUtil = new HttpUtil(); System.out.println(httpUtil.doPost(url));

so I got the reindex process not found error like this

{"error":{"root_cause":[{"type":"reindexing_exception","reason":"Reindexing process 11a9f994-11d1-46c6-9599-a4da5d8764ca is not found."}],"type":"reindexing_exception","reason":"Reindexing process 11a9f994-11d1-46c6-9599-a4da5d8764ca is not found."},"status":500}

I added type for the url like "http://221.231.138.38:9200/law_cloud_v3/cases/_reindex/law_cloud_v4/cases"
and send request use browser and java, the response is the same as above

I use the shield plugin for safed and it seem works correctly with the reindex plugin,
Is it possible to have a relationship with this?

[wuhao000]

my elasticsearch version is the newest 2.1.1

Ummm..., I think Shield plugin might restrict something..
At the moment, CodeLibs plugins do not support Shield plugin.
(Because we do not use it...)

[wuhao000]

thank you for your reply.
I think I can try to remove the shield plugin temporary and reindex again.
and I hope you may consider to add support for shield plugin in the future
