A fluent builder to aid in the construction of
PartitionStrategy s. |
URIBuilder |
Builds dataset and view URIs
|
Enum | Description |
---|---|
CompressionType |
Contains constant definitions for the standard compression types we support.
|
FieldMapping.MappingType |

columns in an HBase table.
|
Exception | Description |
---|---|
ConcurrentSchemaModificationException |
Exception thrown when a schema modification collides with
another client trying to modify the schema of the same
dataset.
|
DatasetException |
Exception thrown for dataset-related failures.
|
DatasetExistsException |
Exception thrown when trying to create a dataset that already exists.
|
DatasetIOException |
Exception thrown for dataset IO-related failures.
|
DatasetNotFoundException |
Exception thrown to indicate that a dataset was not found.
|
DatasetOperationException |
DatasetException thrown when an implementation-specific step fails
and prevents a dataset operation from completing successfully. |
DatasetRecordException |
A DatasetException that signals that an individual record has failed.
|
IncompatibleSchemaException |
Exception thrown when a schema update is not compatible
with the previous schema (or schemas) or with existing
datasets (if shared storage is used, for example).
|
SchemaNotFoundException |
Exception thrown to indicate that there is a problem
finding a particular version of a schema.
|
SerializationException |
Exception thrown when an object cannot be serialized to,
or deserialized from, its binary representation.
|
TypeNotFoundException |
Exception thrown to indicate that there is a problem
finding a given type.
|
UnknownFormatException |
Exception thrown when a Dataset is in an unknown format.
|
ValidationException |
Exception thrown to indicate that there was a problem
parsing or validating a schema, partition strategy, or column mapping.
