Which of the following are the relevant parameters for Hive intermediate result compression? (multiple choice)

A) hive.intermediate.compression.type
B) hive.exec.compress.intermediate
C) hive.exec.compress.output
D) hive.intermediate.compression.codec

2. As the core object of Spark, which of the following characteristics does RDD have? (multiple choice)

A) Partition
B) Fault tolerance

A) For fields that do not need to store the original value, the stored attribute can be set to false.
B) Schema is similar to the table structure in a relational database. It is used to define the structure of index data. It mainly consists of three parts: unlqueKey, Field and FleldType.
C) For a field of the same document, there are multiple values, and they all need to be retained, then the multiValued of the field must be set to true.
D) copyField can be defined as follows: <field name= " cat " type= " string " indexed = " true " stored = " true " docValues= " true " multiValued= " false " /> <field name= " dog " type = " string " indexed = " true " stored = " true " docValues= " true " multi Valued = " false " /> <field name= " text " type= " text_general " indexed = " true " stored = " false " multiValued = " false " /> <copyField source= " cat " dest= " text " maxChars= " 30000 " /> <copyField source= " dog " dest= " text " maxChars = " 30000 " />.
