2.  abstract class FastqRecordReader extends RecordReader[Void, Text]

   A record reader for the interleaved FASTQ format.

   A record reader for the interleaved FASTQ format.

   Reads over an input file and parses interleaved FASTQ read pairs into a single Text output. This is then fed into the FastqConverter, which converts the single Text instance into two AlignmentRecords.

3.  final class InterleavedFastqInputFormat extends FastqInputFormat

   This class is a Hadoop reader for "interleaved fastq" -- that is, fastq with paired reads in the same file, interleaved, rather than in two separate files.

   This class is a Hadoop reader for "interleaved fastq" -- that is, fastq with paired reads in the same file, interleaved, rather than in two separate files. This makes it much easier to Hadoopily slice up a single file and feed the slices into an aligner. The format is the same as fastq, but records are expected to alternate between /1 and /2. As a precondition, we assume that the interleaved FASTQ files are always uncompressed; if the files are compressed, they cannot be split, and thus there is no reason to use the interleaved format.

   This reader is based on the FastqInputFormat that's part of Hadoop-BAM, found at https://github.com/HadoopGenomics/Hadoop-BAM/blob/master/src/main/java/org/seqdoop/hadoop_bam/FastqInputFormat.java

4.  final class SingleFastqInputFormat extends FastqInputFormat

   This class is a Hadoop reader for single read fastq.

   This class is a Hadoop reader for single read fastq.

   This reader is based on the FastqInputFormat that's part of Hadoop-BAM, found at https://github.com/HadoopGenomics/Hadoop-BAM/blob/master/src/main/java/org/seqdoop/hadoop_bam/FastqInputFormat.java
