Removed getCounter for compatibility

getCounter is in a different place in the hierarchy in different versions of hadoop.  Turns out it is different between CDH4.1 and CDH4.2, which doesn't coincide with the hadoop1/hadoop2 split.  Since getCounter is never used in Parquet, I (i.e., @tomwhite) propose to just nix it.  This build works fine for me on CDH4.1.
