I configured the kettle text file output, want to output to the HDFS, installed inside the openFile , according to the tutorial test connection this is correct, but after the choice not to refresh the file list below , or to the hadoop file output, choose good connection definition, point of view shows no connection , don't know what reason be? Have been configure plugins. The properties set to hdp26, hdp26 folder also import some of the cluster configuration file, excuse me, how to solve the great god, thank you!
