----------------------------------
Summary: Remove Preconditions#checkArgument from OM
validateAndUpdateCache
Key: HDDS-12752
URL: https://issues.apache.org/jira/browse/HDDS-12752
Project: Apache Ozone
Issue Type: Task
Reporter: Ivan Andika
Currently, we have some Preconditions#checkArgument and
Preconditions#checkNotNull called inside OMClientRequest#validateAndUpdateCache
which will throw unchecked exceptions and crash the OM. This is because
OMClientRequest#validateAndUpdateCache is called inside the Ratis
StateMachineUpdater which is in charge of applying the commited Raft log
sequentially.
For example OMKeyRequest#prepareMultipartFileInfo contains
Preconditions#checkArgument that the multipartNumber in KeyArgs needs to be >
0. This will throw unchecked exceptions which will crash the OM, although
throwing an OMException would have suffice.
We need to remove the unnecessary Preconditions and only use it if the
Preconditions failure means there is already an unrecoverable OM corruption.
