我使用kbastani/spark-neo4jdocker-compose分析我圖形的中介中心。的Neo4j - Mazerunner工作沒有響應

我的節點建立像這樣:

(n1:Node {id:1})-[r:NEXT {count:100}]->(n2:Node {id:2}) 

我忽略了日誌異常(因爲我不知道如何解決它):

mazerunner_1 | 16/11/29 08:27:51 INFO FileInputFormat: Total input paths to process : 1

我跑我的工作從Neo4j的瀏覽器,像這樣:

:GET /service/mazerunner/analysis/betweenness_centrality/NEXT 

我可以在迷宮流道日誌中看到:

graphdb_1  | /var/lib/neo4j-community-2.2.3/.. 
graphdb_1  | [*] Waiting for messages. To exit press CTRL+C

graphdb_1  | [x] Sent '{"path":"hdfs://hdfs:9000/neo4j/mazerunner/jobs/edgeList.txt","analysis":"betweenness_centrality","mode":"Unpartitioned"}' 

再沒有什麼......半晌。
問:我怎樣才能使它運行?

在我的日誌

16/11/29八點27分51秒INFO FileInputFormat:總輸入路徑的過程:1

那是在闕舊工作。 我不得不刪除HDFS圖像,並重新運行泊塢窗,組成了。它解決了我的問題
