SOLR Zookeeper CLI failing - IOException Packet len is out of range - solr

Question

I wanted to run Security Authentication and Authorization in SOLR 5.3.1 and placed the security.json file in solr root folder but on running the CLI as below :
/cygdrive/c/xampp/htdocs/solr$ server/scripts/cloud-scripts/zkcli.bat -zkhost localhost:8983 -cmd putfile /security.json security.json
I am getting the below issue :
WARN - 2015-10-29 15:39:01.656; org.apache.zookeeper.ClientCnxn$SendThread; Session 0x0 for server frontend.dev/127.0.0.1:8983, unexpected error, closing socket connection and attempting reconnect

I run through the below article :
Zookeeper CLI failing - IOException Packet <len12343123123> is out of range
I followed the instruction to increase the buffer size.I increased it as below for zkcli.bat . The command is as below :
zkcli.bat
#echo off
REM You can override pass the following parameters to this script:
REM
set JVM=java
REM Find location of this script
set SDIR=%~dp0
if "%SDIR:~-1%"=="\" set SDIR=%SDIR:~0,-1%
"%JVM%" -Dlog4j.configuration="file:%SDIR%\log4j.properties" -Djute.maxbuffer="20213486160" -classpath "%SDIR%\..\..\solr-webapp\webapp\WEB-INF\lib\*;%SDIR%\..\..\lib\ext\*" org.apache.solr.cloud.ZkCLI %*
even I set the maxClientCnxns,minSessionTimeout and maxSessionTimeout in zoo.cfg under server\solr :
zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
maxClientCnxns=500
minSessionTimeout=100000
maxSessionTimeout=200000
security.json file is as follows :
{
"authentication":{
"class":"solr.BasicAuthPlugin",
"credentials":{"solr":"IV0EHq1OnNrj6gvRCwvFwTrZ1+z1oBbnQdiVC3otuq0= Ndd7LKvVBAaZIF0QAVi1ekCfAJXr1GGfLtRUXhgrF8c="}
},
"authorization":{
"class":"solr.RuleBasedAuthorizationPlugin",
"user-role":{"solr":"admin"},
"permissions":[{"name":"security-edit",
"role":"admin"}]
}}
I googled but aint get any solution.Please kindly assist what I need to do to make the security authentication and authorization work in SOLR.

Answer 1

I had the same problem, but in my case was that solr 6 was running on normal mode and not in cluster mode. To run solr in cluster mode you need the -c flag.
Then the zookeeper was running on port 911.
./solr status
And see if you have a zookeeper running and in which port
