Hey guys, i am using kafka_2.9.2-0.8.1.1 bin/kafka-topics.sh --zookeeper localhost:2182 --alter --topic my_topic --config log.retention.hours.per.topic=48
It says: Error while executing topic command requirement failed: Unknown configuration "log.retention.hours.per.topic". java.lang.IllegalArgumentException: requirement failed: Unknown configuration "log.retention.hours.per.topic". at scala.Predef$.require(Predef.scala:214) at kafka.log.LogConfig$$anonfun$validateNames$1.apply(LogConfig.scala:138) at kafka.log.LogConfig$$anonfun$validateNames$1.apply(LogConfig.scala:137) at scala.collection.Iterator$class.foreach(Iterator.scala:772) at scala.collection.JavaConversions$JEnumerationWrapper.foreach(JavaConversions.scala:578) at kafka.log.LogConfig$.validateNames(LogConfig.scala:137) at kafka.log.LogConfig$.validate(LogConfig.scala:145) Any idea?
