Josh Elser commented on PHOENIX-5454: ------------------------------------- +1 > Phoenix scripts start foreground java processes as child processes > ------------------------------------------------------------------ > > Key: PHOENIX-5454 > URL: https://issues.apache.org/jira/browse/PHOENIX-5454 > Project: Phoenix > Issue Type: Improvement > Affects Versions: 5.1.0 > Reporter: Istvan Toth > Assignee: Istvan Toth > Priority: Minor > Attachments: PHOENIX-5454.master.v1.patch, > PHOENIX-5454.master.v2.patch > > Time Spent: 20m > Remaining Estimate: 0h > > Currently the phoenix scripts in python start the java process via > subprocess.call() or subprocess.popen() even when the java process has to run > in the foreground, and there is no cleanup required. > I propose that in these cases, we start java via os.exec*(). This has the > following advantages: > * There is no python process idling waiting for the java process to end, > reducing process count and memory consumption > * Signal handling is simplified (signals sent to the starting script are > received by the java process started) > * Return code handling is simplified (no need to check for and return error > codes from java in the startup script) -- This message was sent by Atlassian Jira (v8.3.4#803005)
