TIF needs to be able to set scanner caching size for smaller row tables &
performance
-------------------------------------------------------------------------------------
Key: HBASE-1576
URL: https://issues.apache.org/jira/browse/HBASE-1576
Project: Hadoop HBase
Issue Type: Bug
Components: mapred
Affects Versions: 0.20.0
Reporter: ryan rawson
Priority: Critical
Fix For: 0.20.0
TIF goes with the default scanner caching size (1). When each row is processed
very fast and is small, this limits the overall performance. By setting a
higher scanner caching level you can achieve 100x+ the performance with the
exact same map-reduce and table.
