, Vertex did not succeed due to OWN_TASK_FAILURE, failedTasks:1 killedTasks:28, Vertex vertex_1574056856044_0011_1_02
» Map 1
killed/failed due to:OWN_TASK_FAILURE

DAG did not succeed due to VERTEX_FAILURE. failedVertices:1 killedVertices:0

两个大表进行join操作的时候，一直报如上异常，进排查，原来是Hive的Auto mapjoin的问题，执行语句前加一句

set hive.auto.convert.join = false;

即可解决问题
