    Description

      Calling sync(0); next(...); on a block-compressed SequenceFile.Reader that has already been used may not yield the key-values at the beginning, but those following the previous position. The issue is caused by sync(0) not releasing previously buffered keys and values. The issue was introduced by HADOOP-6196.
