Jesse Yates created HBASE-8684:
----------------------------------
Summary: Table Coprocessor can't access external HTable by default
Key: HBASE-8684
URL: https://issues.apache.org/jira/browse/HBASE-8684
Project: HBase
Issue Type: Bug
Reporter: Jesse Yates
Assignee: Jesse Yates
Fix For: 0.94.9
With the default configuration passed to a RegionCoprocessor environment, you
cannot reach an HTable on the same cluster (at least in 0.94 - no verified yet
in 0.96/8). The reason is in the usage of CompoundConfiguration (backported to
0.94 in HBASE-8176) when loading a table coprocessor we just do
(RegionCoprocessorHost, ln 182):
{code}
Configuration newConf = new Configuration(conf);
// set per-table cfspec properties
{code}
but the conf we pass in a CompoundConfiguration, which means the copy
constructor from Configuration doesn't work at all.
So, we really need two things:
1. A test that we can reach another HTable in the same cluster via a
coprocessor by default
2. Fixing the configuration creation in RegionCoprocessorHost to support (1)
