DRILL-1346: Use HBase table size information to improve scan parallelization
Bugs: DRILL-1346
https://issues.apache.org/jira/browse/DRILL-1346
Repository: drill-git
Description
-------
This patch enables a better estimation of the size of HBase data under scan by
computing the total data size of all regions and sample. This estimation can be
disabled by setting "drill.exec.hbase.scan.sizecalculator.enabled" to false.
