I get ParquetLoader source from github,find bug in this method:
@Override public void setLocation(String location, Job job) throws
IOException { try { JarManager.addDependencyJars(job, Class.forName(
"parquet.Version.class")); } catch (ClassNotFoundException e) { throw new
IOException("Runtime parquet dependency not found", e); }
super.setLocation(location,
job); }


update Class.forName("parquet.Version.class") ----------> Class.forName(
"parquet.Version")-------->compile-------->package------------>deploy

It's OK

thanks
Jack
