Method Detail

getDelimitedProperties

public static java.util.Collection<java.lang.String> getDelimitedProperties()

Gets all the names of the delimited properties that are backed by SerDe properties. A Hive metastore records the delimiter information provided on create using SerDe properties, so we do the same in our model.

Returns:

all HiveTableProperty property names that are part of the ROW FORMAT DELIMITED syntax

getDelimitedSerDeProperties

public static java.util.Collection<java.lang.String> getDelimitedSerDeProperties()

Gets all the names of the SerDe properties that are used to back delimited properties in HiveStorageProperties. A Hive metastore records the delimiter information provided on create using SerDe properties, so we do the same in our model.

Returns:

all SerDe property names that back part of the ROW FORMAT DELIMITED syntax

getDelimitedProperty

public static java.lang.String getDelimitedProperty(java.lang.String serDeProp)

Gets the delimited property on HiveStorageProperties that is stored by the given SerDe property.

Parameters:

serDeProp - the SerDe property

Returns:

the delimited property that is part of the ROW FORMAT DELIMITED syntax

getDelimitedSerDeProperty

public static java.lang.String getDelimitedSerDeProperty(java.lang.String delimitedProp)

Gets the SerDe property that is used to store the given delimited property on HiveStorageProperties.

Parameters:

delimitedProp - the delimited property that is part of the ROW FORMAT DELIMITED syntax

Returns:

the SerDe property that stores the value

refactorValues

public static void refactorValues(java.beans.PropertyChangeEvent colsChange,
                                  HivePartition[] parts)

Takes a change event for a DBObjectID[] property and refactors the change to the given partitions' "values" properties to ensure that they still match the columns.

Parameters:

colsChange - a change event for a DObjectID[] property (assumed to be the columns for the partitions)

parts - the partitions to refactor
