> Currently, when we log statistics, we see something like
> {code}
> 13/01/25 23:16:59 INFO namenode.FSNamesystem: Number of transactions: 0 Total time for
transactions(ms): 0Number of transactions batched in Syncs: 0 Number of syncs: 0 SyncTimes(ms):
0
> {code}
> Notice how the value for total transactions time and "Number of transactions batched
in Syncs" needs a space to separate them.
> FSEditLog#printStatistics:
> {code}
>   private void printStatistics(boolean force) {
>     long now = now();
>     if (lastPrintTime + 60000 > now && !force) {
>       return;
>     }
>     lastPrintTime = now;
>     StringBuilder buf = new StringBuilder();
>     buf.append("Number of transactions: ");
>     buf.append(numTransactions);
>     buf.append(" Total time for transactions(ms): ");
>     buf.append(totalTimeTransactions);
>     buf.append("Number of transactions batched in Syncs: ");
>     buf.append(numTransactionsBatchedInSync);
>     buf.append(" Number of syncs: ");
>     buf.append(editLogStream.getNumSync());
>     buf.append(" SyncTimes(ms): ");
>     buf.append(journalSet.getSyncTimes());
