Hi, I'm trying to upgrade from Solr 5.0 to 5.5. I'm getting the following error:
tail: cannot open `/mnt/ebs2/solrhome/logs/solr.log' for reading: No such file or directory I'm running on CentOS 6.7. The same startup script has been working fine for 5.0 till now. I'm executing as user "solr". In the logs directory, it's able to create solr-8983-console.log and solr_gc.log, so it's not an issue with permission. Does it have to do with JDK version? I'm running the latest oracle java. java version "1.8.0_73" Java(TM) SE Runtime Environment (build 1.8.0_73-b02) Java HotSpot(TM) 64-Bit Server VM (build 25.73-b02, mixed mode) I earlier tried 1.8.0_31 but with no luck. Apparently, Solr 5.0 was running on 1.8.0_31 without any issue. Here's my startup parameter: server -Xss256k -Xms512m -Xmx6144m -XX:NewRatio=3 -XX:SurvivorRatio=4 -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=8 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:ConcGCThreads=4 -XX:ParallelGCThreads=4 -XX:+CMSScavengeBeforeRemark -XX:PretenureSizeThreshold=64m -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=50 -XX:CMSMaxAbortablePrecleanTime=6000 -XX:+CMSParallelRemarkEnabled -XX:+ParallelRefProcEnabled -verbose:gc -XX:+PrintHeapAtGC -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+PrintTenuringDistribution -XX:+PrintGCApplicationStoppedTime -Xloggc:/mnt/ebs2/solrhome/logs/solr_gc.log -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.port=18983 -Dcom.sun.management.jmxremote.rmi.port=18983 -Djava.rmi.server.hostname=54.176.219.134 -DzkClientTimeout=45000 -DzkHost=zoohost1:2181,zoohost2:2181,zoohost3:2181 -Dbootstrap_confdir=./solr/knowledge/conf -Dcollection.configName=myconf -DnumShards=2 -DSTOP.PORT=7983 -DSTOP.KEY=solrrocks -Dhost=54.176.219.134 -Djetty.port=8983 -Dsolr.solr.home=/mnt/ebs2/solrhome/solr -Dsolr.install.dir=/mnt/ebs2/solrhome -Duser.timezone=UTC -Djava.net.preferIPv4Stack=true -Dlog4j.configuration=file:/mnt/ebs2/solrhome/log4j.properties -Dsolr.autoCommit.maxTime=60000 -Dsolr.clustering.enabled=true Not sure what's going wrong. Any pointers will be appreciated. -Thanks, Shamik
