tomscut updated HDFS-16557:
---------------------------
Description:
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.
