enhance zkServer.sh for easier zookeeper automation-izing ---------------------------------------------------------
Key: ZOOKEEPER-905 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-905 Project: Zookeeper Issue Type: Improvement Components: scripts Affects Versions: 3.3.1 Reporter: Nicholas Harteau Priority: Minor Attachments: zkServer.sh.diff zkServer.sh is good at starting zookeeper and figuring out the right options to pass along. unfortunately if you want to wrap zookeeper startup/shutdown in any significant way, you have to reimplement a bunch of the logic there. the attached patch addresses a couple simple issues: 1. add a 'start-foreground' option to zkServer.sh - this allows things that expect to manage a foregrounded process (daemontools, launchd, etc) to use zkServer.sh instead of rolling their own to launch zookeeper 2. add a 'print-cmd' option to zkServer.sh - rather than launching zookeeper from the script, just give me the command you'd normally use to exec zookeeper. I found this useful when writing automation to start/stop zookeeper as part of smoke testing zookeeper-based applications 3. Deal more gracefully with supplying alternate configuration files to zookeeper - currently the script assumes all config files reside in $ZOOCFGDIR - also useful for smoke testing 4. communicate extra info ("JMX enabled") about zookeeper on STDERR rather than STDOUT (necessary for #2) 5. fixes an issue on macos where readlink doesn't have the '-f' option. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
