  /home/hadoop/mydata/hdfs/namenode should be created when executed start-dfs.sh. i had formatted
namenode before doing start-dfs.sh, but no effect.

Please format the namenode and then do start-dfs..

Command for namenode format:

hdfs namenode -format

Thanks & Regards

Are you sure  /home/hadoop/mydata/hdfs/namenode exists and has a right permission?
