Jungtaek Lim updated SPARK-28870:
---------------------------------
Description:
This issue tracks the effort on snapshotting the current status of
KVStore/AppStatusListener and enable incremental reading to speed up replaying
event logs.
This issue will be on top of SPARK-29111 and SPARK-29261, as SPARK-29111 will
add the ability to snapshot/restore from/to KVStore and SPARK-29261 will add
the ability to snapshot/restore of state of (SQL)AppStatusListeners.
Note that both SPARK-29261 and SPARK-29111 will not be guaranteeing any
compatibility, and this issue should deal with the situation: snapshot version
is not compatible with SHS.

Note that both SPARK-29261 and SPARK-29111 will not be guaranteeing any
compatibility, and this issue should deal with two situations as well: 1) some
part of event log files got deleted 2) snapshot version is not compatible with
SHS.
