------------------------------------
Summary: Fix Install Snapshot Notification
Key: RATIS-873
URL: https://issues.apache.org/jira/browse/RATIS-873
Project: Ratis
Issue Type: Bug
Reporter: Hanisha Koneru
Assignee: Hanisha Koneru
This Jira aims to address the following:
# When Follower is in the process of installing snapshot and it gets an append
entry, it replies with result INCONSISTENCY and the follower next index is
updated to the snapshot index being installed. This should not happen as the
snapshot installation is still in progress. Follower's next index on the leader
should remain the same.
# After InstallSnapshot is done, Leader should update the commitIndex of the
Follower to the installed snapshot index.
# After InstallSnapshot, when reloading StateMachine, any previously open
LogSegment should be closed, if the last entry in the open log is already
included in the snapshot.
# When Follower is notified to install snapshot through StateMachine, the reply
should indicate the same. It would help with debugging if the Install Snapshot
success reply and Install Snapshot notified replies are distinct.
