Description

The current log format of printStatistics() is:

2024-04-27 21:15:05,429 [main] INFO  namenode.FSEditLog (FSEditLog.java:printStatistics(801)) - Number of transactions: 2 Total time for transactions(ms): 2 Number of transactions batched in Syncs: 0 Number of syncs: 3 SyncTimes(ms): 1 0

There are no separators between different keys, making it difficult to read. The modified format is：

2024-04-27 21:15:05,429 [main] INFO  namenode.FSEditLog (FSEditLog.java:printStatistics(801)) - Number of transactions: 2, Total time for transactions(ms): 2, Number of transactions batched in Syncs: 0, Number of syncs: 3, SyncTimes(ms): 1 0
