-------------------------------------
Summary: External Exception framework v2 (simplifies and replaces
HBASE-6571)
Key: HBASE-7206
URL: https://issues.apache.org/jira/browse/HBASE-7206
Project: HBase
Issue Type: Sub-task
Reporter: Jonathan Hsieh
This provides a way of sending exceptions from 'external' threads/processes
(not the main executing thread) to others that poll cooperatively for external
exceptions. Some examples of how this can be used include: having a separate
timeout thread that injects an exception when a time limit has elapsed
(TimeoutExceptionInjector, was OperationAttemptTimer), or having an exception
from an separate process delivered to a local thread.
This simplified version is centered around the ExternalException class.
Instead of using generics and ErrorListener interfaces, this more
straight-forward implementation eliminates many of the builders/factories and
generics.
