SequenceFileIterable
public SequenceFileIterable(org.apache.hadoop.fs.Path path,
org.apache.hadoop.conf.Configuration conf)
- Like
SequenceFileIterable(Path, boolean, Configuration)
but key and value instances are not reused
by default.
- Parameters:
path
- file to iterate over
SequenceFileIterable
public SequenceFileIterable(org.apache.hadoop.fs.Path path,
boolean reuseKeyValueInstances,
org.apache.hadoop.conf.Configuration conf)
- Parameters:
path
- file to iterate overreuseKeyValueInstances
- if true, reuses instances of the key and value object instead of creating a new
one for each read from the file
iterator
public Iterator<Pair<K,V>> iterator()
- Specified by:
iterator
in interface Iterable<Pair<K extends org.apache.hadoop.io.Writable,V extends org.apache.hadoop.io.Writable>>
