    2. In the third line from the end of the file, change
      $EXEC "$ROOTDIR/solr/install/bin/solr" $SOLR_START_CMD -cloud -s "$ROOTDIR/solr/data/$i" -p $SCPI -z $HOSTNAME:$ZKPI
      to
      $EXEC "$ROOTDIR/solr/install/bin/solr" $SOLR_START_CMD -cloud -s "$ROOTDIR/solr/data/$i" -p $SCPI -z $HOSTNAME:$ZKPI -Ddisable.configEdit=true
  • On Windows:
    1. Edit C:\IBM\InformationServer\shared-open-source\solr\start-solr.bat
    2. In the third line from the end of the file, change
      "%SOLR_ROOT_DIRECTORY%install\bin\solr.cmd" start -cloud -s "%SOLR_ROOT_DIRECTORY:"=%data\!NODEID!" -p !SCPI! -z %HOSTNAME%:!ZKPI! !FOREGROUND!
      to
