Description

Might be fixed as a byproduct of the fix for HBASE-11766.

Here's what I'm seeing:

• From an endpoint coprocessor on SYSTEM.CATALOG table
• Rows exist in the table, but are all in a single region
• Scan is a new, empty scan created like this: new Scan()
• The following scanner does return data:

      RegionScanner scanner = region.getScanner(scan);
  

• The following scanner does not return any data:

  HTableInterface hTable = env.getTable(region.getTableDesc().getTableName());
  

• The following scanner does return data:

          HTablePool pool = new HTablePool (env.getConfiguration(),1);
          HTableInterface hTable = pool.getTable("SYSTEM.CATALOG");
