FAQ
Hi all,

I have a cluster of 4 machines, in the web HDFS , The last contact of one
machine is very large compared to others. Just as following

Node Last Contact Admin State Size (GB) Used (%) Used (%) Remaining (GB) Blocks
sha-cs-06<http://sha-cs-06:50075/browseDirectory.jsp?namenodeInfoPort=50070&dir=%2F>1In

324.674603 sha-cs-03<http://sha-cs-03:50075/browseDirectory.jsp?namenodeInfoPort=50070&dir=%2F>599In
Service395.223.07

324.833972
Is it normal ? And what exactly Last Contact means ?

Thank you for any help.

Jeff Zhang.
