I've started zookeeper with zkServer.sh
JMX enabled by default
Using config: /home/hduser/zookeeper-3.4.5/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
But when I use
echo ruok | nc 172.20.30.102 2181
It shows nothing but command prompt
zoo.cfg
tickTime=2000
dataDir=/home/hduser/zookeeper
clientPort=2181
java on my sytem
java version "1.6.0_27"

can anyone tell me whats going wrong here?

zkServer.sh status gives

PS C:\kafka2.7>
It looks from log there is a 18000msec timeout defined.Strangely after a few mins when i started kafka server process again i was able to start it without any issues. Note i started zookeeper from zookeper-server-start.bat provided in kafka package rather than apache zookeeper package.
Thanks

I want to disable all zookeeper bootstrap actions for integration test. What gives, I'm frustrated and have no idea what is wrong: why is Zookeeper still trying to run when I disabled it? Thanks in advance.
this should work !

for yaml,
spring:

I am trying to connect to Phoenix via Squirrel client. I am receiving the following logs in the Squirrel logs. The logs suggests that the ClientConnection to zooperkeeper is established however it fails when a SQLClient Connection is being established with a Timeout exception.
I have copied the phoenix client jar into the lib directory of Squirrel and the driver is registered succesfully. Also when I run the SQLLine.py utility in the localhost it loads the SQL commandline to Phoenix succesfully and I can run the commands. Added the phoenix core jars to the $HBASE_HOME/lib folders as well.

I have the same problem, don't find the solution yet, but I managed to use the "thin" client instead.
Start queryserver https://phoenix.apache.org/server.html should listen on port 8765
Copy JAR phoenix-4.6.0-HBase-1.1-thin-client to Squirel lib folder
Create new driver, the class name is "org.apache.phoenix.queryserver.client.Driver"
Connect with this driver (my URI: jdbc:phoenix:thin:url=http://docker:8765)
