Watchdog is using $CHUKWA_HOME while PidFile.java is using CHUKWA_PID_DIR
-------------------------------------------------------------------------
Key: CHUKWA-58
URL: https://issues.apache.org/jira/browse/CHUKWA-58
Project: Hadoop Chukwa
Issue Type: Bug
Reporter: Jerome Boulon
Priority: Blocker
PidFile is using this logic to found where to create the pid file.
String chukwaPath = System.getProperty("CHUKWA_HOME");
StringBuffer pidFilesb = new StringBuffer();
String pidDir = System.getenv("CHUKWA_PID_DIR");
if (pidDir == null) {
pidDir = chukwaPath + File.separator + "var" + File.separator + "run";
}
Watchdog should do something similar instead of using CHUKWA_HOME.
Also, watchdog is difficult to maintain so will be good to create one function
that is doing all the necessary steps
and call that function for all processes that watchdog should watch for.
