Apache Kafka 2.12-1.1.0不适用于JDK -10.0.1

Question

为什么Apache Kafka 2.12-1.1.0无法与JDK 10.0.1一起使用？

./bin/zookeeper-server-start.sh config/zookeeper.properties 
java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)
/..../kafka_2.12-1.1.0/bin/kafka-run-class.sh: line 252: [[: 10 2018-04-17: syntax error in expression (error token is "2018-04-17")
[0.000s][warning][gc] -Xloggc is deprecated. Will use -Xlog:gc:/..../kafka_2.12-1.1.0/bin/../logs/zookeeper-gc.log instead.
Unrecognized VM option 'PrintGCDateStamps'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Answer 1

bin/kafka-run-class.sh用下面的代码更改确实神奇：

在第251行

之前：

JAVA_MAJOR_VERSION=$($JAVA -version 2>&1 | sed -E -n 's/.* version "([^.-]*).*"/\1/p')

后：

JAVA_MAJOR_VERSION=$($JAVA -version 2>&1 | sed -E -n 's/.* version "([^.-]*).*/\1/p')

Answer 2

您可以从文件 kafka-run-class.sh 中删除 java 10 的违规日志记录选项 KAFKA_GC_LOG_OPTS

从

KAFKA_GC_LOG_OPTS="-Xloggc:$LOG_DIR/$GC_LOG_FILE_NAME -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=100M"

到

KAFKA_GC_LOG_OPTS="-Xloggc:$LOG_DIR/$GC_LOG_FILE_NAME -verbose:gc -XX:+PrintGCDetails"
