>
> The idea for a generic inter-process error-handling framework came from
> working on HBASE-6055 (snapshots). Distributed snapshots require tight time
> constraints in taking a snapshot to minimize offline time in face of errors.
> However, we often need to coordinate errors between processes and the current
> Abortable framework is not sufficiently flexible to handle the multitude of
> situations that can occur when coordinating between all region servers, the
> master and zookeeper. Using this framework error handling for snapshots was a
> simple matter, amounting to maybe 200 LOC.
> This seems to be a generally useful framework and can be used to easily add
> inter-process error handling in HBase. The most obvious immediate usage is as
> part of HBASE-5487 when coordinating multiple sub-tasks.
