> When the RegionServer starts, I always find the region logs "Found some outstanding index updates that didn't succeed during WAL replay - attempting to replay now." That is because in following Indexer.postOpen method, the LOG.info in line 528 is before the if statement in line 531, so the method alway log "Found some outstanding index updates that didn't succeed..." no matter whether there are outstanding index updates.
