Viraj Jasani reopened HBASE-24831: ---------------------------------- Reopening since this is breaking source compatibility by removing protected methods of IA.Public org.apache.hadoop.hbase.mapreduce.TableRecordReaderImpl. Checked PR discussion but compatibility is not mentioned. Maybe an oversight? > Avoid invoke Counter using reflection in SnapshotInputFormat > ------------------------------------------------------------- > > Key: HBASE-24831 > URL: https://issues.apache.org/jira/browse/HBASE-24831 > Project: HBase > Issue Type: Improvement > Reporter: Yechao Chen > Assignee: Yechao Chen > Priority: Major > Labels: Performance, mapreduce, snapshot > Fix For: 3.0.0-alpha-1, 2.4.0, 2.3.2 > > > In TableRecordReaderImpl we invoke Counter increment by reflection > This will be called nextKeyValue() in TableSnapshotInputFormat > reflection invoke is very slower than normal method call > we can avoid these to improve the read performance -- This message was sent by Atlassian Jira (v8.3.4#803005)
