metatech commented on ZOOKEEPER-2078:
-------------------------------------
Sorry, my previous comment was wrong : the error "invalid signal specification"
really prevents the "stop" command from being processed, and the Zookeeper
instance is still running (altough its PID file is removed).
Also, a "zkServer.sh start" while the process is running does not detect that
it is already running.
> zkServer.sh uses pattern unsupported by "grep" on Solaris
> ---------------------------------------------------------

> Key: ZOOKEEPER-2078
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2078
> Project: ZooKeeper
> Issue Type: Bug
> Components: scripts
> Affects Versions: 3.4.5
> Environment: Solaris 11
> Reporter: metatech
> Priority: Minor
>
> The script "zkServer.sh" contains a pattern (POSIX "character class syntax")
> which is not supported by "grep" on Solaris (both versions 10 and 11).
> {code}
> ZOO_DATADIR="$(grep "^[[:space:]]*dataDir" "$ZOOCFG" | sed -e 's/.*=//')"
> {code}
> This results into the environment variable being set with an empty value,
> which later gives the following error :
> {code}
> Starting zookeeper ... bin/zkServer.sh: line 114: /zookeeper_server.pid:
> Permission denied
> {code}
> The workaround is to simplify the pattern used by "grep" :
> {code}
> ZOO_DATADIR="$(grep "^dataDir" "$ZOOCFG" | sed -e 's/.*=//')"
> {code}
> The same pattern is also used in the "status" command, which fails to read
> the "clientPort", which results into the following error :
> {code}
> Error contacting service. It is probably not running.
> {code}
