Stephen Chu updated HDFS-4444:
------------------------------
Description:
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());
LOG.info(buf);
}
{code}
