[jira] [Commented] (HBASE-7412) IncreasingToUpperBoundRegionSplitPolicy may not use the right region flush size

    [ https://issues.apache.org/jira/browse/HBASE-7412?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13537473#comment-13537473 ] 

Jimmy Xiang commented on HBASE-7412:
------------------------------------

HTableDescriptor#getMaxFileSize and HTableDescriptor#getMemStoreFlushSize return defaults if not set.  The caller checks if the returned value is the same as the default, if so, it assumes it is not set, which may not be right, because the value could happen to be the same as the default.

> If the region flush size is not set in the table, IncreasingToUpperBoundRegionSplitPolicy will most likely always use the default value: 128MB, even if the flush size is set to a different value in hbase-site.xml.
