Waiting mechanism for node manager to start about biemond-orawls HOT 6 CLOSED

Hi ,

that is indeed much better than a sleep. Hope you will send me a pull request

thanks

Unfortunately, I am not currently allowed to submit to open source projects, that is the bad part of this.

Ok, no problem.

I think this can work https://github.com/fiddyspence/puppet-sleep

but I am only thinking checking for a running process is not enough, the first time can take a while, probably need to check with netstat if the nodemanager is listening on that port

Very cool, that looks (by description) to be exactly what I was referring to. I like it a lot!

This will be the code

sleep is a parameter you can set your own value, default = 20 and will check for every 2 seconds

exec { "startNodemanager ${title}":
  command     => "nohup ${startHome}/startNodeManager.sh &",
  environment => [ $env, "JAVA_HOME=${jdk_home_dir}", 'JAVA_VENDOR=Oracle' ],
  unless      => $checkCommand,
  path        => $exec_path,
  user        => $os_user,
  group       => $os_group,
  cwd         => $nodeMgrHome,
}

sleep { "wake up ${title}":
  bedtime       => $sleep,
  wakeupfor     => "/bin/netstat -lnt | /bin/grep ':${nodemanager_port}'",
  dozetime      => 2,
  failontimeout => true,
  subscribe     => Exec["startNodemanager ${title}"],
  refreshonly   => true,
}

Very good, sir! The only other question would be whether or not you want to make the dozetime configurable (not that it buys you a whole lot really). But, this is definitely very nice.
