konnte anstelle von minReplication (= 1) nur auf 0 Knoten repliziert werden. Es werden 4 Datenknoten ausgeführt, und in dieser Operation werden keine Knoten ausgeschlossen.
Ich weiß nicht, wie ich diesen Fehler beheben kann:
Vertex failed, vertexName=initialmap, vertexId=vertex_1449805139484_0001_1_00, diagnostics=[Task failed, taskId=task_1449805139484_0001_1_00_000003, diagnostics=[AttemptID:attempt_1449805139484_0001_1_00_000003_0 Info:Error: org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /user/hadoop/gridmix-kon/input/_temporary/1/_temporary/attempt_14498051394840_0001_m_000003_0/part-m-00003/segment-121 could only be replicated to 0 nodes instead of minReplication (=1). There are 4 datanode(s) running and no node(s) are excluded in this operation.
