Hello Shawn,
Firstly thank you for reply & your article - was using your article as a
reference before I even tried making this change.
I used the installer script to install. Im starting solr as sudo service
solr restart
Interestingly, I believe the other parameters are being set from
/etc/default/solr.in.sh.
For example , ZK_HOST, SOLR_HEAP, SOLR_OPTS but just the GC parameters seem
to be off.
This is how /etc/default/solr.in.sh looks like
SOLR_HEAP="6g"
# Enable verbose GC logging
GC_LOG_OPTS="-verbose:gc -XX:+PrintHeapAtGC -XX:+PrintGCDetails \
-XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+PrintTenuringDistribution
-XX:+PrintGCApplicationStoppedTime"
# These GC settings have shown to work well for a number of common Solr
workloads
GC_TUNE="-XX:+UseG1GC -XX:+UseStringDeduplication"
ZK_HOST="zk-1.XXXXX.int:2181"
# Set the ZooKeeper client timeout (for SolrCloud mode)
ZK_CLIENT_TIMEOUT="15000"
# By default the start script uses UTC; override the timezone if needed
#SOLR_TIMEZONE="UTC"
SOLR_OPTS="$SOLR_OPTS -Xss256k"
SOLR_HOME=/opt/solr/data
LOG4J_PROPS=/opt/solr/server/resources/log4j.properties
SOLR_LOGS_DIR=/opt/solr/logs
SOLR_PORT=8983
SOLR_MODE=solrcloud
Here is the output of sudo service solr status
Found 1 Solr nodes:
