zookeeper linux下无法启动的问题
在linux下安装zookeeper时，出现了如下的错误：
-
[hadoop
@hadoop
-master bin]$ ./zkServer.sh start
-

-

发现没有找到java.lang.management下的一个方法。如果使用的是标准的JDK的话，不应该出现这样的错误的。于是查看zkServer.sh的脚本。发现启动java程序的脚本如下：
-
java
"-Dzookeeper.log.dir=${ZOO_LOG_DIR}"
"-Dzookeeper.root.logger=${ZOO_LOG4J_PROP}"
\
-
-cp "$CLASSPATH"
$JVMFLAGS $ZOOMAIN
"$ZOOCFG"
&
在linux下直接执行java命令，发现输出如下：
-
[hadoop@hadoop-master bin]$ java
-
Usage: gij [OPTION] ... CLASS [ARGS] ...
-
to invoke CLASS.main, or
-
gij -jar [OPTION] ... JARFILE [ARGS] ...
-
to execute a jar file
-
Try `gij --help' for more information.
显然，zkServer.sh使用的java不正确。使用的gij的java。解决这个问题就简单了，把脚本改成：
-
$JAVA_HOME/bin/java
"-Dzookeeper.log.dir=${ZOO_LOG_DIR}"
"-Dzookeeper.root.logger=${ZOO_LOG4J_PROP}"
\
-
-cp "$CLASSPATH"
$JVMFLAGS $ZOOMAIN
"$ZOOCFG"
&
这样修改之后，就能正常运行了。
