[jira] [Updated] (HBASE-13989) Threshold for combined MemStore and
BlockCache percentages is not checked
[ https://issues.apache.org/jira/browse/HBASE-13989?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ted Yu updated HBASE-13989:
---------------------------
Description:
In HeapMemoryManager#doInit():
{code}
globalMemStorePercentMinRange = conf.getFloat(MEMSTORE_SIZE_MIN_RANGE_KEY,
globalMemStorePercent);
globalMemStorePercentMaxRange = conf.getFloat(MEMSTORE_SIZE_MAX_RANGE_KEY,
globalMemStorePercent);
...
if (globalMemStorePercent == globalMemStorePercentMinRange
&& globalMemStorePercent == globalMemStorePercentMaxRange) {
return false;
}
{code}
If memory tuning is not specified, globalMemStorePercentMinRange and globalMemStorePercentMaxRange would carry the value of globalMemStorePercent.
This would make doInit() exit before checking the threshold for combined MemStore and BlockCache percentages.
