Vertex failed, vertexName=Map 1, vertexId=vertex_1497551165160_3893578_1_00, diagnostics=[Vertex vertex_1497551165160_3893578_1_00 [Map 1] killed/failed due to:ROOT_INPUT_INIT_FAILURE, Vertex Input: summary initializer failed, vertex=vertex_1497551165160_3893578_1_00 [Map 1], java.io.IOException: Couldn't create proxy provider class org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider

executed above SQL command in Hive, and saw the job stuck in initializing stage, and an error saying: Adapter operation failed: 500: failed to fetch result from proxy. The command was working few weeks back, but not now.

Any insight on this issue would be appreciated
