Yiping Han resolved HADOOP-2360.
--------------------------------
Resolution: Cannot Reproduce
> hadoop::RecordReader::read() throws exception in HadoopPipes::RecordWriter
> --------------------------------------------------------------------------
>
> Key: HADOOP-2360
> URL: https://issues.apache.org/jira/browse/HADOOP-2360
> Project: Hadoop
> Issue Type: Bug
> Affects Versions: 0.14.3
> Reporter: Yiping Han
> Priority: Minor
>
> The jute record is in format:
> class SampleValue
> {
> ustring data;
> }
> And in HadoopPipes::RecordWriter::emit(), has code like this:
> void SampleRecordWriterC::emit(const std::string& key, const std::string&
> value)
> {
> if (key.empty() || value.empty()) {
> return;
> }
> hadoop::StringInStream key_in_stream(const_cast<std::string&>(key));
> hadoop::RecordReader key_record_reader(key_in_stream, hadoop::kCSV);
> EmitKeyT emit_key;
> key_record_reader.read(emit_key);
> hadoop::StringInStream value_in_stream(const_cast<std::string&>(value));
> hadoop::RecordReader value_record_reader(value_in_stream, hadoop::kCSV);
> EmitValueT emit_value;
> value_record_reader.read(emit_value);
> return;
> }
> And the code throw hadoop::IOException at the read() line.
> In the mapper, I have faked record emitted by the following code:
> std::string value;
> EmitValueT emit_value;
> emit_value.getData().assign("FakeData");
> hadoop::StringOutStream value_out_stream(value);
> hadoop::RecordWriter value_record_writer(value_out_stream, hadoop::kCSV);
> value_record_writer.write(emit_value);
> We haven't update to the up-to-date version of hadoop. But I've searched the
> tickets and didn't find one issuing this problem.
