Description

    [javac] /.../snip.java:201: setOutputFormatClass(java.lang.Class<? extends org.apache.hadoop.mapreduce.OutputFormat<?,?>>) in \
        org.apache.hadoop.mapreduce.Job cannot be applied to (java.lang.Class<org.apache.hadoop.mapreduce.lib.output.SequenceFileOutputFormat>)
    [javac]     job.setOutputFormatClass(SequenceFileOutputFormat.class);
    [javac]        ^

The signatures for get{Input,Output}FormatClass are probably too restrictive:

  public void setOutputFormatClass(Class<? extends OutputFormat<?,?>> cls) throws IllegalStateException
