Constructor Detail

SequenceFileValueIterable

public SequenceFileValueIterable(org.apache.hadoop.fs.Path path,
                                 org.apache.hadoop.conf.Configuration conf)

Like SequenceFileValueIterable(Path, boolean, Configuration) but instances are not reused by default.

Parameters:

path - file to iterate over

SequenceFileValueIterable

public SequenceFileValueIterable(org.apache.hadoop.fs.Path path,
                                 boolean reuseKeyValueInstances,
                                 org.apache.hadoop.conf.Configuration conf)

Parameters:

path - file to iterate over

reuseKeyValueInstances - if true, reuses instances of the value object instead of creating a new one for each read from the file
