> 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 always log "Found some outstanding index updates that didn't succeed..."
no matter whether there are outstanding index updates.
