Hi, I have a created a table with fields defined as varchar(length). Is it correct to insert data in to the table casting the fields as VARCHAR(length).
I am getting this error. Error occurred executing hive query: OK FAILED: SemanticException Generate Map Join Task Error: Class cannot be created (missing no-arg constructor): org.apache.hadoop.hive.serde2.objectinspector.primitive.WritableHiveVarcharObjectInspector Serialization trace: objectInspector (org.apache.hadoop.hive.ql.exec.ColumnInfo) signature (org.apache.hadoop.hive.ql.exec.RowSchema) rowSchema (org.apache.hadoop.hive.ql.exec.FileSinkOperator) childOperators (org.apache.hadoop.hive.ql.exec.SelectOperator) childOperators (org.apache.hadoop.hive.ql.exec.GroupByOperator) opParseCtxMap (org.apache.hadoop.hive.ql.plan.MapWork) mapWork (org.apache.hadoop.hive.ql.plan.MapredWork) Please Help! Thanks in advance, UPD
