Description

RATIS-589 added a check in SegmentedRaftLogWorker to ensure raft.server.log.write.buffer.size >= raft.server.log.appender.buffer.byte-limit + 8.

Ozone needs to be updated to pass that check.

OM and SCM:

IllegalArgumentException: raft.server.log.write.buffer.size (= 8388608) is less than raft.server.log.appender.buffer.byte-limit + 8 (= 33554440)

DN:

IllegalArgumentException: raft.server.log.write.buffer.size (= 2097152) is less than raft.server.log.appender.buffer.byte-limit + 8 (= 33554440)
