Yang Yun commented on HDFS-15384: --------------------------------- Thanks [~ayushtkn] for the answer. It's reasonable to open a DFSInputStream with '{{read.prefetch.size', but for the method getLocatedBlocks, if you don't read the code,it's hard to know that it has a limition. }} > Method getLocatedBlocks(String src, long start) of DFSClient only return > partial blocks > --------------------------------------------------------------------------------------- > > Key: HDFS-15384 > URL: https://issues.apache.org/jira/browse/HDFS-15384 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Yang Yun > Assignee: Yang Yun > Priority: Minor > Attachments: HDFS-15384.001.patch > > > > > Intuitively, the method getLocatedBlocks(String src, long start) of DFSClient > will return all blocks after offset ‘start’.
