Ted Yu commented on HBASE-21247:
--------------------------------
We are aware of the above (existing) config.
However, it is an enum. Meaning, hbase has to know the implementation.
This issue adds the ability for third party to plug in WAL provider without
hbase hardcoding the implementation.
> Allow WAL Provider to be specified by configuration without explicit enum in
> Providers

> Currently all the WAL Providers acceptable to hbase are specified in
> Providers enum of WALFactory.
> This restricts the ability for additional WAL Providers to be supplied - by
> class name.
> This issue introduces additional config which allows the specification of new
> WAL Provider through class name.
