Hemant Kumar updated HDDS-9685:
-------------------------------
Description:
As fix of HDDS-9199, exceptions in snapshot chain creation were changed ISE and
same is thrown back from OMSnapshotCreateRequest.
https://github.com/apache/ozone/blob/master/hadoop-ozone/ozone-manager/src/main/java/org/apache/hadoop/ozone/om/request/snapshot/OMSnapshotCreateRequest.java#L282
Because of this, if snapshot creation fails due to snapshot chain corruption,
OMSnapshotCreateRequest throws IllegalStateException which is not handled by
the state machine.
This task is to handle IllegalStateException properly in
OMSnapshotCreateRequest so that state machine can handle it properly.
