Motivation

  • When using FileSystem Offloader, and you set the ledger retention policy, after the offloaded ledger is outdated, however the data can not be deleted from file system. This is because the datafile path is wrong.

  • For example, in fact the datafile path is "file:///Users/pulsar_nfs/public/default/persistent/test_pulsar_delta/449-775f0961-9719-4658-8357-6b0edbdef7a3", but is mistaken formatted as "file:///Users/pulsar_nfs/null/449-775f0961-9719-4658-8357-6b0edbdef7a3".

  • The reason is when format the data path, "ManagedLedgerName" property in "offloadDriverMetadata" is missing.

Modifications

  • Before format the data path, add "ManagedLedgerName" property in "offloadDriverMetadata" map.

Verifying this change

  • Make sure that the change passes the CI checks.

I will add a new unit test to cover this.

if the offloadDriverMetadata generated by Collections.emptyMap(), and then call put operation, it will throw the following exception:

java.lang.UnsupportedOperationException
	at java.util.AbstractMap.put(AbstractMap.java:209)

I wonder why this is not caught by existing unit tests.
It would be better to add a test that cover this code.
