-------------------------------------
Summary: Make LedgerMetadata Immutable
Key: BOOKKEEPER-822
URL: https://issues.apache.org/jira/browse/BOOKKEEPER-822
Project: Bookkeeper
Issue Type: Bug
Reporter: Ivan Kelly
Fix For: 4.4.0, 4.3.1
Mutable metadata has been a very rich source of bugs. There are multiple
processing modifying for rebuilding ensembles, closing, fencing, autorecovery
etc.
The local metadata should be a mirror of the metadata in zookeeper. So we
should only modify the local metadata as a whole. The first part of this is
making it immutable, so that it can only be modified with a builder.
