我正在尝试将zookeeper从3.4.8升级到3.4.13。
在升级/usr/lib/zookeeper
drwxr-xr-x 5 root root 4.0K Aug 23 08:39 .
drwxr-xr-x 77 root root 12K Aug 23 08:50 ..
drwxr-xr-x 2 root root 4.0K Aug 23 08:39 bin
lrwxrwxrwx 1 root root 19 May 24 11:25 conf -> /etc/zookeeper/conf
drwxr-xr-x 2 root root 4.0K Aug 23 08:39 lib
-rw-r--r-- 1 root root 12K May 24 11:25 LICENSE.txt
-rw-r--r-- 1 root root 170 May 24 11:25 NOTICE.txt
-rw-r--r-- 1 root root 1.3M Aug 23 08:39 zookeeper-3.4.8.jar
lrwxrwxrwx 1 root root 38 Aug 23 08:39 zookeeper.jar -> /usr/lib/zookeeper/zookeeper-3.4.8.jar
如answer中所述，我已从此link下载了Zookeeper，并将zookeeper-3.4.13.jar放在/usr/lib/zookeeper中，并指出了如下所示的符号链接
lrwxrwxrwx 1 root root 39 Aug 30 03:19 zookeeper.jar -> /usr/lib/zookeeper/zookeeper-3.4.13.jar
但是在重新设置Zookeeper后检查状态时，它仍然指向3.4.8
ubuntu@vrni-platform:/etc/zookeeper/conf$ telnet localhost 2181
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
status
Zookeeper version: 3.4.8--1, built on 02/06/2016 03:18 GMT
看来这是因为从/usr/lib/zookeeper/bin/zkEnv.sh加载罐子的方式
#release tarball format
for i in "$ZOOBINDIR"/../zookeeper-*.jar
do
CLASSPATH="$i:$CLASSPATH"
done
可以让我知道这是zkEnv.sh的某个已知问题吗？这是预期的吗？
