Class Summary |
CodecPool |
A global compressor/decompressor pool used to save and reuse
(possibly native) compression/decompression codecs. |
FlatFileInputFormat<T> |
An InputFormat for Plain files with Deserializer records |
FlatFileInputFormat.RowContainer<T> |
A work-around until HADOOP-1230 is fixed. |
FlatFileInputFormat.SerializationContextFromConf<S> |
An implementation of FlatFileInputFormat.SerializationContext that reads the Serialization class and
specific subclass to be deserialized from the JobConf. |
HiveFileFormatUtils |
An util class for various Hive file format tasks. |
HiveIgnoreKeyTextOutputFormat<K extends WritableComparable,V extends Writable> |
HiveIgnoreKeyTextOutputFormat replaces key with null before feeding the to TextOutputFormat.RecordWriter. |
HiveIgnoreKeyTextOutputFormat.IgnoreKeyWriter<K extends WritableComparable,V extends Writable> |
|
HiveInputFormat<K extends WritableComparable,V extends Writable> |
HiveInputFormat is a parameterized InputFormat which looks at the path name and determine
the correct InputFormat for that path name from mapredPlan.pathToPartitionInfo(). |
HiveInputFormat.HiveInputSplit |
HiveInputSplit encapsulates an InputSplit with its corresponding inputFormatClass. |
HiveKey |
HiveKey is a simple wrapper on Text which allows us to set the hashCode easily. |
HiveKey.Comparator |
A Comparator optimized for HiveKey. |
HiveRecordReader<K extends WritableComparable,V extends Writable> |
|
HiveSequenceFileOutputFormat |
A HiveOutputFormat that writes SequenceFile s. |
IgnoreKeyTextOutputFormat<K extends WritableComparable,V extends Writable> |
Deprecated. use HiveIgnoreKeyTextOutputFormat instead} |
IgnoreKeyTextOutputFormat.IgnoreKeyWriter<K extends WritableComparable,V extends Writable> |
|
NonSyncDataInputBuffer |
A thread-not-safe version of Hadoop's DataInputBuffer, which removes all
synchronized modifiers. |
NonSyncDataOutputBuffer |
A thread-not-safe version of Hadoop's DataOutputBuffer, which removes all
synchronized modifiers. |
RCFile |
RCFile s, short of Record Columnar File, are flat files
consisting of binary key/value pairs, which shares much similarity with
SequenceFile . |
RCFile.Reader |
Read KeyBuffer/ValueBuffer pairs from a RCFile. |
RCFile.Writer |
Write KeyBuffer/ValueBuffer pairs to a RCFile. |
