The "ControllerServer" page has been changed by AaronMcCurry: https://wiki.apache.org/blur/ControllerServer New page: = Controller Server Configuration = * [[#blursite|blur-site.properties]] * [[#blurenv|blur-env.sh]] <<Anchor(blursite)>> == blur-site.properties == These are the default settings for the shard server that can be overridden in the blur-site.properties file. Consider increasing the various thread pool counts (`*.thread.count`). The `blur.controller.server.remote.thread.count` is very important to increase for larger clusters, basically one thread is used per shard server per query. Some production cluster have used set this thread pool to 2000 or more threads. {{{ blur.controller.hostname= blur.controller.bind.address=0.0.0.0 blur.controller.bind.port=40010 blur.controller.server.thrift.thread.count=32 blur.controller.server.remote.thread.count=64 blur.controller.remote.fetch.count=100 blur.controller.retry.max.fetch.retries=3 blur.controller.retry.max.mutate.retries=3 blur.controller.retry.max.default.retries=3 blur.controller.retry.fetch.delay=500 blur.controller.retry.mutate.delay=500 blur.controller.retry.default.delay=500 blur.controller.retry.max.fetch.delay=2000 blur.controller.retry.max.mutate.delay=2000 blur.controller.retry.max.default.delay=2000 blur.query.max.results.fetch=1000 blur.query.max.row.fetch=100 blur.query.max.record.fetch=1000 blur.gui.controller.port=40080 blur.metrics.reporters= }}} <<Anchor(blurenv)>> == blur-env.sh == {{{ # JAVA JVM OPTIONS for the controller servers, jvm tuning parameters are placed here. # Consider adding the -XX:OnOutOfMemoryError="kill -9 %p" option to kill jvms that are failing due to memory issues. export BLUR_CONTROLLER_JVM_OPTIONS="-Xmx1024m -Djava.net.preferIPv4Stack=true " # Time to sleep between controller server commands. export BLUR_CONTROLLER_SLEEP=0.1 # The of controller servers to spawn per machine. export BLUR_NUMBER_OF_CONTROLLER_SERVER_INSTANCES_PER_MACHINE=1 }}}
