Is this the last error message in the log? You have an on-disk index named "data" that contains a field with a period in its name. That was okay prior to ES 2.0 but is no longer allowed. You have to reindex that data to rename the field before you can run ES 2.0 or later.
ok
but when i run on terminal. for eg:-
root@sab-VirtualBox:~# /opt/logstash/bin/logstash -e 'input { stdin { } } output { elasticsearch {hosts =>'localhost' } }'
hi. how r u
Settings: Default pipeline workers: 1
Connection refused {:class=>"Manticore::SocketException", :level=>:error}
Logstash startup completed
Attempted to send a bulk request to Elasticsearch configured at '["http://localhost:9200/"]', but Elasticsearch appears to be unreachable or down! {:error_message=>"Connection refused", :class=>"Manticore::SocketException", :client_config=>{:hosts=>["http://localhost:9200/"], :ssl=>nil, :transport_options=>{:socket_timeout=>0, :request_time
yes its last error message.
But if ES isn't starting up properly, why would you think Logstash would be able to connect to it?
Downgrade ES, reindex the "data" index to rename all fields with periods in their name, run the migration plugin to find any other incompatibilities, then retry the upgrade.
ok.thanks.i try.
Is there any document regarding migration plugin?please refer.
For me, googling "elasticsearch migration plugin" has this as the first hit: https://github.com/elastic/elasticsearch-migration
thanks. nw i installed migration plugin and check it.
when i run in browser the message is
All checks completed successfully.
Elasticsearch version: 1.7.5
can i upgrade ES 2.3 version?
i install ELK by Deb .
can i use same procedure?
Yes, an upgrade should be as simple as upgrading the Debian package and restarting ES (I don't think the init script does that for you).
after upgrade there is error in elasticsearch log file regarding migration plugin.
should i again install migration plugin for upgrade version?
java.lang.IllegalStateException: Could not load plugin descriptor for existing plugin [migration]. Was the plugin built before 2.0?
You can uninstall the migration plugin after the upgrade.
ok.
thanks
i remove migration plugin but there is another error in elasticsearch log file that is:-
java.lang.IllegalStateException: unable to upgrade the mappings for the index [bad], reason: [No handler for type [murmur3] declared on field [foo]]
what should i do?
Thanks for ur support. i install mapping plugin and elasticsearch work.
