Slider has to run the Solr servers on random ports because it can't control where they are started (more than one might be started on the same host). The next release of Slider will have an anti-affinity container placement option, so that might help. You should be able to connect to each of the Solr instances that Slider creates. ... View more

I guess this is a design limitation of the LucidWorks solr app package. One thing you'd have to do to avoid losing data on restart is to configure Solr to store its data in HDFS. You might be able to do this by setting the solr_opts parameter in the appConfig: -Dsolr.directoryFactory=HdfsDirectoryFactory -Dsolr.lock.type=none -Dsolr.hdfs.confdir=/etc/hadoop/conf -Dsolr.hdfs.home=${DEFAULT_DATA_DIR} You would also need to configure automatic failover when creating the collection: curl "http://server:port/solr/admin/collections?action=CREATE&name=collection_name&numShards=2&autoAddReplicas=true" ...

Another thing I noticed is that memory requested is pretty high if you're going to be running it on a VM. It might not be launching Solr because it doesn't have enough memory. I made the these changes to appConfig and resources and was able to get Solr running on a VM that has 9GB of RAM. You might need to make additional adjustments for your setup, and also make sure yarn.scheduler.minimum-allocation-mb isn't too high. ... View more

ZK_HOST and AGENT_WORK_ROOT will be replaced by Slider. The AGENT_WORK_ROOT will have the form /hadoop/yarn/local/usercache/<userName>/appcache/<appID>/<containerID> (where /hadoop/yarn/local is the directory specified by the yarn.nodemanager.local-dirs in yarn-site.xml). Based on the solr_node.py script, it looks like the output of the Solr start command should end up in the slider-agent logs in the container log directory. If containers are failing to launch, information about that should be in the AM log, slider.log in the log directory for container 0001. ... View more

The directory ${AGENT_WORK_ROOT}/app/install/solr-* will be created for you by Slider. Slider will untar your Solr tarball to the ${AGENT_WORK_ROOT}/app/install directory. That's why Slider needs to know the name of the directory contained in your tarball. ... View more
