Yes, it is supported by Hadoop sequence file. It is splittable
by default. If you have installed and specified LZO correctly,
use these:
org.apache.hadoop.mapreduce.lib.output.SequenceFileOutputForma
t.setCompressOutput(job,true);
org.apache.hadoop.mapreduce.lib.output.SequenceFileOutputForma
t.setOutputCompressorClass(job,com.hadoop.compression.lzo.LzoC
odec.class);
org.apache.hadoop.mapreduce.lib.output.SequenceFileOutputForma
t.setOutputCompressionType(job,
SequenceFile.CompressionType.BLOCK);
job.setOutputFormatClass(org.apache.hadoop.mapreduce.lib.outpu
t.SequenceFileOutputFormat.class);
