errors when starting the 2nd node

I am evaluating percona cluster to see if we should use it, but I have getting the following errors when starting the 2nd node. Please help.

Look likes netcat is not installed which is required for streaming backups. http://www.percona.com/doc/percona-xtrabackup/2.1/howtos/recipes_ibkx_stream.html
$ sudo yum install netcat (RHEL/CentOS)
$ sudo aptitude install netcat (Ubuntu/Debian)

After installing netcat, retry starting node2.

Hi mifan,
Is netcat same as nc? I installed that and it didn’t help. I also changed the wsrep_sst_method from xtrabackup to rsync, but still having problem starting the 2nd node.
Thanks,
Manny
