             Summary: sync(0); next(); yields wrong key-values on block-compressed files
                 Key: HADOOP-13214
                 URL: https://issues.apache.org/jira/browse/HADOOP-13214
             Project: Hadoop Common
          Issue Type: Bug
          Components: io
            Reporter: Illes S


Calling {{sync(0); next(...);}} on a block-compressed {{SequenceFileReader}} 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
