@Sanjay Gurnani I have meet the same problem as you, and resolved by setting the spark config `spark.sql.orc.impl=native` but when i read data by creating external hive table, it occured an erros like this Bad status for request TFetchResultsReq(fetchType=0, operationHandle=TOperationHandle(hasResultSet=True, modifiedRowCount=None, operationType=0, operationId=THandleIdentifier(secret='71\xc7\xc6\x14\xc5NZ\x94W\x881\x15\x9b\xbf\xd4', guid='\xfe*}z\x7f5O\xae\x93\x1a\x80P\xd9\xba\xb8~')), orientation=4, maxRows=100):

results=None, hasMoreRows=None) my hive version is 1.1.0-cdh5.7.1 and my create table sql is like this create external table orc_test ( key string, value string, topic string, partition int, offset bigint, timestamp timestamp, timestampType int ) STORED AS ORC LOCATION '/data/orc_test'; could you show me some detail on reading data by hive sql thanks ...
