@liangyepianzhou I proposed some suggestions to make the instructions easier
to read and understand by changing the ordered/unordered list plus other minor
fixes. To provide a comprehensive understanding, you can preview my suggestions
as follows.
The offloaded data is stored as `MapFile` in the following new path of the
filesystem:
…
* `storageBasePath` is the value of `hadoop.tmp.dir`, which is configured
in `broker.conf` or `filesystem_offload_core_site.xml`.
* `managedLedgerName` is the ledger name of the persistentTopic manager.
...
You can use the following method to get `managedLedgerName`.
…
To read data out as ledger entries from the filesystem, complete the
following steps.
1. Create a reader to read both `MapFile` with a new path and the
`configuration` of the filesystem.
...
2. Read the data as `LedgerEntry` from the filesystem.
...
3. Deserialize the `ledgerEntry` to `Message`.
...
Note that the capitalization of `LedgerEntry` in step2 and `ledgerEntry` in
step3 is different, which may confuse users.
