Related to the revert of the ScanRanges change, you'll need to make this
change to prevent the SkipRangeParallelIteratorRegionSplitter from being used
(as you always need to scan all regions for a local index). Cleanest might be
to just implement a simple ParallelIteratorRegionSplitter for use when a local
index is used that just returns all regions:
public class ParallelIteratorRegionSplitterFactory {
public static ParallelIteratorRegionSplitter
getSplitter(StatementContext context, TableRef table, HintNode hintNode) throws
SQLException {
if (!isLocalIndex &&
context.getScanRanges().useSkipScanFilter()) {
return
SkipRangeParallelIteratorRegionSplitter.getInstance(context, table, hintNode);
}
return
DefaultParallelIteratorRegionSplitter.getInstance(context, table, hintNode);
}
}

> Hindex(https://github.com/Huawei-Hadoop/hindex) provides local indexing
> support to HBase. It stores region level index in a separate table, and
> co-locates the user and index table regions with a custom load balancer.
> See http://goo.gl/phkhwC and http://goo.gl/EswlxC for more information.
> This JIRA addresses the local indexing solution integration to phoenix.
