Can splitLogWorkerCoordination be null and the reason? Thanks.

splitlogworkercoordination is only present when we are doing the old zk based log splitting. Otherwise, it is null.

+1 on this fix, I hit this issue and figure out if we set HBASE_SPLIT_WAL_COORDINATED_BY_ZK in TestClusterRestartFailoverSplitWithoutZk, the test fails.

server.getCoordinatedStateManager() == null ? null
: server.getCoordinatedStateManager().getSplitLogWorkerCoordination();
if (!WALSplitter.splitLogFile(walDir, fs.getFileStatus(new Path(walDir, filename)), fs, conf,
p, sequenceIdChecker, splitLogWorkerCoordination, factory, server)) {
return Status.PREEMPTED;
