Workarounds and Mitigations
You may apply any published fix, or disable the ConfigAPI if not in use, by
running Solr with the system property "disable.configEdit=true".
The following steps should be done:
a) Fix the Solr server start script:
o On UNIX:
1. Edit /opt/IBM/InformationServer/shared-open-source/solr/start-solr.sh
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
o 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
"%SOLR_ROOT_DIRECTORY%install\bin\solr.cmd" start -cloud -s
"%SOLR_ROOT_DIRECTORY:"=%data\!NODEID!" -p !SCPI! -z %HOSTNAME%:!ZKPI!
!FOREGROUND! -Ddisable.configEdit=true
b) Follow the instructions in Step 2 of Technote to restart the
InfoSrvZookeeper, InfoSrvKafka and InfoSrvSolrCloud services.
