Description
why is there many times register ,that will make bookie out of memory
When i change 3 3 2 to 2 2 2 after reduce bookie nodes from 5 to 2
ZK has a lots of ledgers mate data infos, and the 2 bookie nodes had old data.
Running bookies cluster that has two nodes, without running any producers or consumers.
some minutes or hours later , watching the memory info of one bookie using jstat:
and dump info using mat
the class ReadOnlyLedgerHandle will register a listener to AbstractZkLedgerManager's listeners field when init. some times later listeners filed will occupy a lot of heap memory
