> As we kept adding more granular block read and block cache usage statistics,
> a combinatorial explosion of various cases to monitor started to happen,
> especially when we wanted both per-table/column family/block type statistics
> and aggregate statistics on various subsets of these dimensions. Here, we
> un-clutters HFile readers, LruBlockCache, StoreFile, etc. by creating a
> centralized class that knows how to update all kinds of per-table/CF/block
> type counters.
> Table name and column family configuration have been pushed to a base class,
> SchemaConfigured. This is convenient as many of existing classes that have
> these properties (HFile readers/writers, HFile blocks, etc.) did not have a
> base class. Whether to collect per-(table, columnFamily) or per-columnFamily
> only metrics can be configured with the hbase.metrics.showTableName
> configuration key. We don't expect this configuration to change at runtime,
> so we cache the setting statically and log a warning when an attempt is made
> to flip it once already set. This way we don't have to pass configuration to
> a lot more places, e.g. everywhere an HFile reader is instantiated.
> Thanks to Liyin for his initial version of per-table metrics patch and a lot
> of valuable feedback.
