-----------------------------------
Summary: UIMA-DUCC: Agent should verify results from ps cmd when
detecting rogue processes
Key: UIMA-4826
URL: https://issues.apache.org/jira/browse/UIMA-4826
Project: UIMA
Issue Type: Bug
Components: DUCC
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.1.0-Ducc
When collecting user processes the Agent spawns ps command and gathers results.
Under some circumstance the OS ps command may not provide correct results for
user id. Sometimes it returns user id instead of user name.
Modify the ps command to use
pb = new ProcessBuilder("ps","-Ao","user:12,pid,ppid,uid,user:12,args",
"--no-heading");
upon return check result of parse and compare user[0] to user[4]. Both should
match. If different dont collect user data and do another ps command.
As an extra check, make sure the user is not uid. If is all numeric, throw away
results and try again.
