"failed to parse, document is empty" Error

[syunusic]

I have installed ES 2.2.
I tried installing the one that appears in the README:

$ $ES_HOME/bin/plugin install org.codelibs/elasticsearch-reindexing/2.1.1

And also compiling it, in order to use pom.xml that appears to support 2.2.
When I execute it, this is what I get:

$ curl -XPOST localhost:9200/oldindex/_reindex/newindex/
{"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}

And in /var/log/elaticsearch/node.log, this is that I see:

[2016-03-03 15:16:40,773][INFO ][rest.suppressed          ] /oldindex/_reindex/newindex/ Params: {index=oldindex, id=newindex, type=_reindex}
RemoteTransportException[[elastic-1][172.16.87.59:9300][indices:data/write/index]]; nested: RemoteTransportException[[elastic-1][172.16.87.59:9300][indices:data/write/index[p]]]; nested: MapperParsingException[failed to parse, document is empty];

The index exists and has documents in it.

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

I think plugin installation was failed.

Here is what I see:

$ sudo bin/plugin install org.codelibs/elasticsearch-reindexing/2.1.1

Installed reindexing into /usr/share/elasticsearch/plugins/reindexing

and then:

$ ls /usr/share/elasticsearch/plugins/reindexing
elasticsearch-reindexing-2.1.1.jar  plugin-descriptor.properties

It seems ok to me.

Hmmm… it doesn’t appear:

$ curl 'localhost:9200/_cat/plugins?v'
name        component version type url
elastic-gui head      master  s    /_plugin/head/

:-?

I think elasticsearch's log file contains warn or error messages.
