Ted Yu commented on HBASE-21247:
--------------------------------
w.r.t. first comment above,
{code}
boolean metaWALProvPresent = conf.get(META_WAL_PROVIDER_CLASS) != null;
provider = createProvider(getProviderClass(
metaWALProvPresent ? META_WAL_PROVIDER_CLASS : WAL_PROVIDER_CLASS,
{code}
when META_WAL_PROVIDER_CLASS is not specified, we fall back to the value for
WAL_PROVIDER_CLASS (if present).
The user doesn't need to specify two WAL classes in the normal case.
> 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.
