      Work Description: tomscut opened a new pull request, #4219:
URL: https://github.com/apache/hadoop/pull/4219

   JIRA: HDFS-16557.
   
   The lastTxId of an inprogress EditLogInputStream lastTxId isn't necessarily 
HdfsServerConstants.INVALID_TXID. We can determine its status directly by 
EditLogInputStream#isInProgress.
   
   For example, when bootstrapStandby, the EditLogInputStream of inProgress is 
misjudged, resulting in a gap check failure, which causes bootstrapStandby to 
fail.
