re indexing not works

[veeruborra]

I created a index with mappings and stored 3020 documents in it.
Now i created another index with mappins and changed type for one field.Now i am trying to move only data from oldindex to newindex.After the process completes no data is shown in new index.

curl -XPOST localhost:9200/admin_logs421/_reindex/admin_logs422?wait_for_completion=true

the error is

{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"failed to parse, document is empty"}],"type":"mapper_parsing_exception","reason":"failed to parse, document is empty"},"status":400}

Installation of Reindexing Plugin seems to be failed.

Params: {id=newindex, index=oldindex, type=_reindex}

elasticsearch handles _reindex as type.
Please check if the plugin is installed correctly.

I installed 2.1.1 as a plugin in ES 2.1.1.

$ bin/plugin list
Installed plugins in /home/hadoop/elasticsearch/elasticsearch-2.1.1/plugins:
    - kopf
    - reindexing
    - repository-hdfs
    - cloud-aws
    - hq

$ curl -XGET 'http://ip-172-31-12-242:9200/_reindex'
{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"No feature for name [_reindex]"}],"type":"illegal_argument_exception","reason":"No feature for name [_reindex]"},"status":400}
