> 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.
