> The lastTxId of an inprogress EditLogInputStream lastTxId isn't necessarily
> HdfsServerConstants.INVALID_TXID. We can determine its status directly by
> EditLogInputStream#isInProgress.
> We introduced [SBN READ], and set
> {color:#ff0000}{{dfs.ha.tail-edits.in-progress=true}}{color}. Then
> bootstrapStandby, the EditLogInputStream of inProgress is misjudged,
> resulting in a gap check failure, which causes bootstrapStandby to fail.
