Even with the change skip scan will be used James. The change is required
because the key ranges generated by compiler won't be in the local index
regions key range because local index rows have prefixed region start key
extra. Without the change mostly no region will be selected for scanning.
QueryIT#testSimpleInListStatement is the test case verifies the same.
Here is the explain query result.
CLIENT PARALLEL 4-WAY SKIP SCAN ON 2 KEYS OVER _LOCAL_IDX_ATABLE [-32768,2]
- [-32768,4]
SERVER FILTER BY FIRST KEY ONLY AND ORGANIZATION_ID = '00D300000000XHP'

> 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.
