Running adam-gfa

Transform GFA 1.0 to generic Gfa1Record records in Parquet format

$ spark-submit \
    --class com.github.heuermh.adam.gfa.Gfa1ToDataframe \
    target/adam-gfa_2.12-${version}.jar \
    in.gfa \
    out.parquet

Transform GFA 1.0 to specific Containment, Link, Path, Segment, and Traversal records in Parquet format

$ spark-submit \
    --class com.github.heuermh.adam.gfa.Gfa1ToDataframes \
    target/adam-gfa_2.12-${version}.jar \
    in.gfa \
    out

(creates separate out.containments.parquet, out.links.parquet, out.paths.parquet, out.segments.parquet, and out.traversals.parquet directories)
