Review request for Ambari, Dmitro Lisnichenko and Vitalyi Brodetskyi.
Bugs: AMBARI-12548
https://issues.apache.org/jira/browse/AMBARI-12548
Repository: ambari
Description
-------
The agent executes the "df" command when it starts up.
In rare scenarios, this command can hang (can even hanging for several days
without any timeout). When this happens the agent won't move forward to the
process of registration, etc.
There's an ambari-server property called agent.check.mounts.timeout. This can
be defined to force a timeout.
However, we should always have a default timeout on the agent script side, even
if this property is not defined to avoid a situation where the agent is
completely hung.
