Peter Linnell created BIGTOP-574:
------------------------------------
Summary: Add netcat and fuser as dependencies for some of the
Bigtop stack.
Key: BIGTOP-574
URL: https://issues.apache.org/jira/browse/BIGTOP-574
Project: Bigtop
Issue Type: Bug
Components: General
Affects Versions: 0.3.0
Reporter: Peter Linnell
Priority: Minor
Fix For: 0.4.0
The SshFenceByTcpPort class assumes that netcat (nc) and fuser will be
available on the ssh target. fuser is in /sbin and is probably always
installed, but I've definitely seen CentOS boxes without netcat installed. We
could force installation by listing it as a package requirement, which I
suspect would be a good thing.
