the class HiveConnectorPartitionService method savePartitions.

/**
 * By default(checkIfExists=true and aletrIfExists=false), this method adds the provided list of partitions.
 * If a partition already exists, it is dropped first before adding it.
 * If checkIfExists=false, the method adds the partitions to the table. If a partition already exists,
 * an AlreadyExistsException error is thrown.
 * If alterIfExists=true, the method updates existing partitions and adds non-existant partitions.
 * If a partition in the provided partition list has all the details, then it is used. If the details are missing,
 * then the table details are inherited. This is mostly for the storage information.
