----------------------------------

             Summary: HLogSplitter can retry to open a 0-length hlog file
                 Key: HBASE-8314
                 URL: https://issues.apache.org/jira/browse/HBASE-8314
             Project: HBase
          Issue Type: Bug
            Reporter: Jimmy Xiang
            Assignee: Jimmy Xiang


In case a HLog file is of size 0, and it is under recovery, HLogSplitter will fail to open it since it can get the file length, therefore, master can't start.
