--------------------------------------------
Summary: Select query with LIMIT clause can fail if their are
marker files like "_SUCCESS" and "_MANIFEST"
Key: HIVE-27071
URL: https://issues.apache.org/jira/browse/HIVE-27071
Project: Hive
Issue Type: Bug
Components: HiveServer2
Affects Versions: 4.0.0
Reporter: Sai Hemanth Gantasala
Assignee: László Bodor
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

Hive execution engine should ignore these marker files while reading the
table/partition data.
