> Spark clients creates marker files like "_SUCCESS" and "_MANIFEST" under the table/partition path at the end of a write operation. For example 'hdfs://name-node-host/table/partition/_SUCCESS'
> Whenever Hive is trying to read that table with the LIMIT clause, it could to the following error:
> {code:java}
> ERROR : Vertex failed, vertexName=Map 1, vertexId=vertex_1676095298574_0017_2_00, diagnostics=[Vertex vertex_1676095298574_0017_2_00 [Map 1] killed/failed due to:ROOT_INPUT_INIT_FAILURE, Vertex Input: trade initializer failed, vertex=vertex_1676095298574_0017_2_00 [Map 1], org.apache.hadoop.mapred.InvalidInputException: Input path does not exist: hdfs://name-node-host/table/partition/_MANIFEST
