I want to execute below code,but it is highlighting error in code with red in vi. Getting error after sudo ssh -t root@$ip << EOF line .Where have I scripted wrongly?

#!/bin/bash

cassandra_home=$(python -c "import json; print ",".join(json.load(open('${repair.json}','r'))["cassandra_home"])")

iplist[@]=$(python -c "import json; print ",".join(json.load(open('${repair.json}','r'))["iplist"])")

for ip in ${iplist[@]}

do

  sudo ssh -t root@$ip << EOF

    for ip in ${iplist[@]} 

    do

      echo Checking $ip for ongoing repairs

      ${cassandra_home}nodetool -h $ip tpstats | grep Repair#

      response=$?

      if [ $response -eq 0 ]; then

        repair_ongoing=true

        echo "Ongoing repair on $ip"

      fi

    done 

    if ! [ $repair_ongoing ]; then

      ## echo "Taking a snapshot."

      ## ${cassandra_home}bin/nodetool -h $ip snapshot

      echo "Starting repair on $ip"

      start=$(date +%s)

      ${cassandra_home}bin/nodetool -h $ip repair -pr -inc -local metadata

      sleep 3

      ${cassandra_home}bin/nodetool -h $ip cleanup metadata 

      end=$(date +%s)

      #echo "ks.tab,st,et,last run,status">>repair_status.csv

      echo "Repair and cleanup completed for metadata in $((end - start)) seconds"

    fi

    exit 0

  EOF

done           

Use https://www.shellcheck.net/ (there is a vim plugin)
It would tell you

Line 18:

  EOF

 ^-- SC1039: Remove indentation before end token (or use <<- and indent with tabs).

Then go on to list many other issues.

You are trying to store an array of values in iplist[@] but as a static declaration...

Try as follows:

#!/bin/bash

cassandra_home=(`python -c "import json; print ",".join(json.load(open('${repair.json}','r'))["cassandra_home"])"`)

iplist[@]=(`python -c "import json; print ",".join(json.load(open('${repair.json}','r'))["iplist"])`)

for ip in ${iplist[@]}

do

  sudo ssh -t root@$ip "

    for ip in ${iplist[@]} 

    do

      echo Checking $ip for ongoing repairs

      ${cassandra_home}nodetool -h $ip tpstats | grep Repair#

      response=$?

      if [ $response -eq 0 ]; then

        repair_ongoing=true

        echo "Ongoing repair on $ip"

      fi

    done 

    if ! [ $repair_ongoing ]; then

      ## echo "Taking a snapshot."

      ## ${cassandra_home}bin/nodetool -h $ip snapshot

      echo "Starting repair on $ip"

      start=`date +%s`

      ${cassandra_home}bin/nodetool -h $ip repair -pr -inc -local metadata

      sleep 3

      ${cassandra_home}bin/nodetool -h $ip cleanup metadata 

      end=`date +%s`

      #echo "ks.tab,st,et,last run,status">>repair_status.csv

      echo "Repair and cleanup completed for metadata in $end - $start seconds"

    fi

    exit 0"
