After formatting the FS and starting namenode,datanode and
secondarynamenode , i am getting below warning in SecondaryNameNode logs.
*WARN org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode: Checkpoint
Period :3600 secs (60 min)*
Please help to debug this.

you can ignore this on 2 node cluster.
This value means time it waits between two periodic checkpoints on
secondary namenode.
