             Summary: Separate the config of block size when we do log 
splitting and write Hlog
                 Key: HBASE-20986
                 URL: https://issues.apache.org/jira/browse/HBASE-20986
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 2.1.0
            Reporter: Jingyun Tian
             Fix For: 2.1.0


Since the block size of recovered edits and hlog are the same right now, if we 
set a large value to block size, name node may not able to assign enough space 
when we do log splitting. But set a large value to hlog block size can help 
reduce the number of region server asking for a new block. Thus I think 
separate the config of block size is necessary.
