                                                                  String hiveConfDir)

Returns a new HiveConf.

Parameters:

hiveConfDir - Hive conf directory path.

Returns:

A HiveConf instance.

isEmbeddedMetastore

public static boolean isEmbeddedMetastore(org.apache.hadoop.hive.conf.HiveConf hiveConf)

Check whether the hive.metastore.uris is empty

getPartitionKeys

public static List<String> getPartitionKeys(org.apache.flink.table.catalog.CatalogTable table)

Returns the partition key list with given table.

inferPartitionPath

public static String inferPartitionPath(boolean hiveStylePartitioning,
                                        org.apache.flink.table.catalog.CatalogPartitionSpec catalogPartitionSpec)

Returns the partition path with given CatalogPartitionSpec.

                                                                        org.apache.hadoop.hive.conf.HiveConf hiveConf,

Returns a list of ordered partition values by re-arranging them based on the given list of partition keys. If the partition value is null, it'll be converted into default partition name.

Parameters:

partitionSpec - The partition spec

partitionKeys - The partition keys

tablePath - The table path

Returns:

A list of partition values ordered by partition keys

Throws:

org.apache.flink.table.catalog.exceptions.PartitionSpecInvalidException - thrown if partitionSpec and partitionKeys have different sizes, or any key in partitionKeys doesn't exist in partitionSpec.
