[jira] [Updated] (HBASE-28601) Enable setting memstore on-heap sizes in bytes

     [ https://issues.apache.org/jira/browse/HBASE-28601?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Nick Dimiduk updated HBASE-28601:
---------------------------------
    Description: Specifying blockcache and memstore sizes as a percentage of heap is not always ideal. Sometimes it's easier to specify exact values rather than backing into a percentage. Let's introduce new configuration settings (perhaps named similarly to {{hbase.bucketcache.size}}) that accept byte values. Even nicer would be if these settings accepted human-friendly byte values like {{512m}} or {{10g}}.   (was: Specifying blockcache and memcache sizes as a percentage of heap is not always ideal. Sometimes it's easier to specify exact values rather than backing into a percentage. Let's introduce new configuration settings (perhaps named similarly to {{hbase.bucketcache.size}}) that accept byte values.

        Summary: Enable setting memstore on-heap sizes in bytes  (was: Enable setting memcache on-heap sizes in bytes)

Arg. I meant "memstore". Thanks for pointing it out, [~liuxiaocs7].
