Password do not work in bookkeeper
Hi everyone,
I'm using bookkeeper but I meet some problems. When I createLedger by a
password(A) and addEntry into it, everything is OK. And I can open the
ledger with password(A) and read the content. But what's the strange, I can
open the ledger with any password. Can anyone tell me what's the possible
reason? I notice that in the document of Release 4.1, the password argument
is in String, but in the real API, it only accept byte[], so I use
password.getBytes() as the parameters. Is it right?
Another question, when I administrate a Bookkeeper cluster, is there any
tools to help me clean all the data from one or every bookie?

This is the case with CRC32 on 4.0 and 4.1.
CRC32 is only there to provide a checksum on the data. In this case,
the password is only used to ensure that users don't accidently
overwrite each others ledgers.
MAC uses HMAC, and this will give an error if you try to read with the
wrong key.

Ivan

Thank you,
But actually, I can read all the entries, but I'm not sure if the
contents are right. When I call entries= ledgerHandler.readEntries, the
result is not empty and entries.hasMoreElements() is true

Hello ChenWei,

For 4.1, you could open the ledger. It expected that you should not read
any entries from the ledger. Could you read any entries using a wrong
password?

as the parameters
It accepts only bytes. Which document you referred? The javadoc?
> when I administrate a Bookkeeper cluster, is there any tools to help me
clean all the data from one or every bookie?
In 4.2.0 (not released yet), we provided bookieformat and metaformat to
help formatting a bookkeeper cluster.
