Using shell generate an unexpected cookie

[tal705]

BUG REPORT

Describe the bug

When I run the order "bookkeeper shell cookie_generate", I got a new cookie, but this new cookie is different from the other cookie in zk.

Order( It belongs to pulsar ) :
./bin/bookkeeper shell cookie_generate -j data2/bookkeeper/journal -l data2/bookkeeper/ledgers -i 9285da1b-e1be-471b-8d11-d30d80212e68 -o /tmp/cookie.x 10.254.3.60:3181

The generated cookie is this:
4
bookieHost: "10.254.17.8:3181"
journalDir: "data2/bookkeeper/journal"
ledgerDirs: "data2/bookkeeper/ledgers"
instanceId: "3ed785b5-eb93-498c-9d57-b38ab8846e7b"

The cookie in zk is this :
4
bookieHost: "10.254.17.8:3181"
journalDir: "data/bookkeeper/journal"
ledgerDirs: "1\tdata/bookkeeper/ledgers"
instanceId: "3ed785b5-eb93-498c-9d57-b38ab8846e7b"

We can find the difference is "1\t" in two ledgerDirs, because of it, After I changed the dir and others operation, starting bookie is fail.

To Reproduce

As BUG says

Expected behavior

When I generate the cookie by the shell way, It should include "1\t"

this is a nasty problem, I am sorry.
maybe you can work around the problem just by using a sym link from data2 to data.
if your original problem is to expand bookie capacity you can add the new directory to the configuration and enable 'storage expansion', this way the bookie will start using the new directory as well

@eolivelli I think this is a bug we should fix.

@sijie sure that is clear
