--------------------------------
Summary: Catalog manager tasks are edge-triggered
Key: KUDU-1997
URL: https://issues.apache.org/jira/browse/KUDU-1997
Project: Kudu
Issue Type: Bug
Components: master
Affects Versions: 1.3.1
Reporter: Mike Percy
Catalog manager tasks are edge-triggered (based on a response to a tablet
report) instead of level-triggered (based on periodic state polling).
The upshot of this (original) design is that when there is a master failover,
ongoing tasks will stop being retried.
Examples of these tasks include things like adding a new replica, deleting an
evicted replica, etc. See SendDeleteReplicaRequest() and SendAddServerRequest()
in the code base for examples.
