fix issue: stop kafka or zookeeper failed when full command length reach
4096 bytes
when user want to stop the zookeeper or kafka server, they will exec the
script kafka-server-stop.sh or kafka-server-stop.sh.
In kafka-server-stop.sh and kafka-server-stop.sh, it get the pid with ps
command, as below:
PIDS=$(ps ax | grep -i 'kafka.Kafka' | grep java | grep -v grep | awk
'{print $1}')
PIDS=$(ps ax | grep java | grep -i QuorumPeerMain | grep -v grep | awk
'{print $1}')
Since linux limit process command in 4096 bytes, the above command will
fail when the user install kafka in a folder with long path, just like
"/opt/bigdata/kafka_2.10-0.10.0.0".
To fix this issue, we need to modify it as below:
step1. modify kafka-run-class.sh, add -D parameter to the command;
for kafka ,it is : java -Dproc_kafkaServer
for zookeeper, it is : java -Dproc_zookeeper
step2. modify kafka-server-stop.sh and kafka-server-stop.sh, get the PID
with -D parameter information.
if [ -z "$PIDS" ]; then
PIDS=$(ps ax | grep java | grep -i proc_kafkaServer| grep -v grep | awk
'{print $1}')
fi
if [ -z "$PIDS" ]; then
PIDS=$(ps ax | grep java | grep -i proc_zookeeper| grep -v grep | awk
'{print $1}')
fi
