There was a problem hiding this comment.
maybe we need to fix the bk bug, but the PR still makes sense

Motivation
Bookie has bugs that Ledger may close with a zero length, even if it has entries, such as [fix] Write stuck due to pending add callback by multiple threads bookkeeper#4557. See example[1]
Since a Pulsar message at least contains message metadata, Pulsar will never write entries to BKs with an empty payload, we can confirm the ledger will never be empty when
ledger.entreisis larger than0.The offloading tasks checks both
ledger lengthandentries, which prevents offloading and throws an errorjava.util.concurrent.CompletionException: java.lang.IllegalArgumentException: An empty or open ledger should never be offloaded[1]: ledger close with a zero length, but it has
320entriesModifications
Skip the checking of
ledger.length, just checkledger.entres, and print a warn log if a ledger's length is not expected,Documentation
