Eu SSH em uma máquina virtual Ubuntu remota e tentei carregar alguns dados usando o seguinte comando:
$ curl -X 'POST' -H 'Content-Type:application/json' -d @quickstart/wikiticker-index.json localhost:8090/druid/indexer/v1/task
curl: (7) Failed to connect to localhost port 8090: Connection refused
O que devo fazer para me conectar?
Segue-se o que eu estou executando nesse diretório:
java 'cat conf-quickstart/druid/historical/jvm.config | xargs' -cp "conf-quickstart/druid/_common:conf-quickstart/druid/historical:lib/*" io.druid.cli.Main server historical
java 'cat conf-quickstart/druid/broker/jvm.config | xargs' -cp "conf-quickstart/druid/_common:conf-quickstart/druid/broker:lib/*" io.druid.cli.Main server broker
java 'cat conf-quickstart/druid/coordinator/jvm.config | xargs' -cp "conf-quickstart/druid/_common:conf-quickstart/druid/coordinator:lib/*" io.druid.cli.Main server coordinator
java 'cat conf-quickstart/druid/overlord/jvm.config | xargs' -cp "conf-quickstart/druid/_common:conf-quickstart/druid/overlord:lib/*" io.druid.cli.Main server overlord
java 'cat conf-quickstart/druid/middleManager/jvm.config | xargs' -cp "conf-quickstart/druid/_common:conf-quickstart/druid/middleManager:lib/*" io.druid.cli.Main server middleManager
Depois de executar cada linha java... acima, começou a repetir o seguinte:
