回答1:

just omit the "start" parameter and call "bin\zkServer" instead.

java.lang.NumberFormatException: For input string: "C:\Development\apps\zookeeper\zookeeper3.4.1\bin..\conf\zoo.cfg"

It seems you run the zkServer with the "start" and the location of the zoo.cfg file, namely, "C:\Development\apps\zookeeper\zookeeper3.4.1\bin..\conf\zoo.cfg", and another parameter, which adds up to 3 parameters:

./zkServer start C:\Development\apps\zookeeper\zookeeper3.4.1\bin..\conf\zoo.cfg xxx

So, the problem can be solved by simply remove the second and third parameter, which makes the command to:

./zkServer start

The reason behind this is because the classes(QuorumPeerMain, ZooKeeperServerMain) zkServer uses to initialize the zookeeper system accept various number of parameters and behave accordingly. When you feed two parameters to zkServer, the meaning behind the two parameters supposed to be port and datadir. Yeah, port should be a number, and here comes your bomb.

BTW, the bootstrap scripts are coming with help instructions when you execute them without any para.

回答3:

In zoo.cfg file goto dataDir=/usr/zookeeper/data

In data folder create a file with name myid and write 1. Save the file and start zkServer

If you are running multiple instances, for every instance you need to create myid file in data folder and write with 1,2,3 respectively. Actually this is used for node leader election.
