stack updated HADOOP-2377: -------------------------- Attachment: bigger.patch Made regions 4 times larger by default. They're now 256M instead of 64M. Also upped memcache size threshold from 16M to 64M. Tests show splits taking same time -- split time shouldn't be effected by time -- and compactions taking about a third longer: 20-30 seconds instead of 8-10 seconds (They run in background). Running the PerformanceEvaluation test, before we ended up w/ 19 regions doing write test-- now 5. M src/contrib/hbase/conf/hbase-default.xml Upped flush.size and max.filesize M src/contrib/hbase/src/test/org/apache/hadoop/hbase/PerformanceEvaluation.java Don't delete table on end of test and don't do auto-upload of content.... just fail if none there. M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HStoreFile.java readSplitInfo: Looks like a leak. M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HConstants.java Up region MAX_FILE_SIZE to 256M. M src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegion.java Up flush size to 64M > [hbase] Holding open MapFile.Readers is expensive, so use less of them > ---------------------------------------------------------------------- > > Key: HADOOP-2377 > URL: https://issues.apache.org/jira/browse/HADOOP-2377 > Project: Hadoop > Issue Type: Improvement > Components: contrib/hbase > Reporter: stack > Fix For: 0.16.0 > > Attachments: bigger.patch > > -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
