             Summary: Node kill pkill commands failing in some envs
                 Key: HRJS-28
                 URL: https://issues.jboss.org/browse/HRJS-28
             Project: Infinispan Javascript client
          Issue Type: Enhancement
    Affects Versions: 0.3.0
            Reporter: Galder Zamarreño


On certain environments (e.g. Ubuntu), tests involving killing nodes are failing with errors like this:

{code}
  1) Infinispan cluster client can failover when nodes crash
   Message:
     Error: Command failed: /bin/sh -c pkill -9 -f '.*java.*node4 .*'

   Stacktrace:
     Error: Command failed: /bin/sh -c pkill -9 -f '.*java.*node4 .*'

    at ChildProcess.exithandler (child_process.js:213:12)
    at emitTwo (events.js:87:13)
    at ChildProcess.emit (events.js:172:7)
    at maybeClose (internal/child_process.js:821:16)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:211:5)
...
  5) Infinispan xsite cluster client can manually switch and fail over sites
   Message:
     Error: Command failed: /bin/sh -c pkill -9 -f '.*java.*node-site-a .*'

   Stacktrace:
     Error: Command failed: /bin/sh -c pkill -9 -f '.*java.*node-site-a .*'

    at ChildProcess.exithandler (child_process.js:213:12)
    at emitTwo (events.js:87:13)
    at ChildProcess.emit (events.js:172:7)
    at maybeClose (internal/child_process.js:821:16)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:211:5)
{code}

After doing some debugging, we discovered that the error itself contains this info:

{code}
{"killed":false,"code":null,"signal":"SIGKILL","cmd":"/bin/sh -c pkill -9 -f '.*java.*node4 .*'"}
{code}

According to the docu:
{code}
If the process terminated normally, code is the final exit code of the process, otherwise null. If the process terminated due to receipt of a signal, signal is the string name of the signal, otherwise null.
{code}

So, it would appear that {{pkill}} is killing itself? 

The easiest workaround here might be to ignore any errors.
