ChenKai created HBASE-21594:
-------------------------------

             Summary: Requested block is out of range when reading hfile
                 Key: HBASE-21594
                 URL: https://issues.apache.org/jira/browse/HBASE-21594
             Project: HBase
          Issue Type: Bug
          Components: HFile
    Affects Versions: 0.98.10
            Reporter: ChenKai


My HFiles are generated by Spark HBaseBulkLoad. And then when i read a few of 
them(or hbase do compact), i encounter the following exceptions.

 
{code:java}
Exception in thread "main" java.io.IOException: Requested block is out of 
range: 77329641, lastDataBlockOffset: 77329641, 
trailer.getLoadOnOpenDataOffset: 77329641

Looks like `lastDataBlockOffset` is equals to 
`trailer.getLoadOnOpenDataOffset`. Could anyone help me? Thanks very much.
