Only one coprocessor of each priority type can be loaded for a table
--------------------------------------------------------------------
Key: HBASE-3624
URL: https://issues.apache.org/jira/browse/HBASE-3624
Project: HBase
Issue Type: Bug
Components: coprocessors
Affects Versions: 0.92.0
Environment: Standalone HBase, linux
Reporter: Jesse Daniels
Coprocessors are added to HBase using a TreeSet that is initialized with an
EnvironmentPriorityComparator. The net effect is that only one coprocessor of a
given priority can be loaded at a time for a given table. This appears to be
due to how the TreeSet uses the EnvironmentPriorityComparator to determine
whether there are duplicate entries - if the coprocessors have the same
priority (e.g., User), they are considered the same and won't be added to the
Set.
