I have SequenceFiles I'd like to convert to HFile. How do I that?
Hi Igor,
I will say, MapReduce.
SequenceFileInputFormat
HFileOutputFormat

That's the kind of solution I'm looking for.
Here is what I have:
String jobName = "Seq2HFile";
Job job = new Job(getConf(), jobName);
job.setJarByClass(Seq2HFile.class);
job.setMapperClass(*MyIdentityMapper.class*);
job.setMapOutputKeyClass(BytesWritable.class);
job.setM
Sounds like hbase's HFileOutputFormat depends on KeyValue's "family" field.
I don't want that.
All I want is to keep keys and values in an indexed filed. TFile would work
as well. But it seems there is no TFileOutputFormat available.

Hi Igor,
Have you looked at this constructor?
/**
* Constructs KeyValue structure filled with null value.
* @param row - row key (arbitrary byte array)
* @param family family name
* @param qualifier column qualifier
*/
public KeyValue(final byte [] row, final byte [] family,
Hi JM,
My usage is the following: I want to write a C++ program which will answer
RPC requests. Each request has a list of keys and responses will contain
values. I want to use HFile because it has an efficient key-based index and
because there is a whole set of tools in hadoop to produce this kin
