>
> The HBase block cache size parameter is editable through Ambari. But HBase
> verifies whether the sum of the value specified for hfile.block.cache.size and
> hbase.regionserver.global.memstore.upperLimit doesn't exceed 0.8 when it
> starts. We would want to make the memstore variables
> (hbase.regionserver.global.memstore.upperLimit and
> hbase.regionserver.global.memstore.upperLimit) editable or at least adjust
> these values automatically if the user changes the block cache size (may not
> be a preferable option).
