WALUtil.doFullAppendTransaction(WAL wal,
NavigableMap<byte[],Integer> replicationScope,
HRegionInfo hri,
WALEdit edit,
MultiVersionConcurrencyControl mvcc,

A 'full' WAL transaction involves starting an mvcc transaction followed by an append,
an optional sync, and then a call to complete the mvcc transaction.
|
static WALKey |
WALUtil.writeBulkLoadMarkerAndSync(WAL wal,
NavigableMap<byte[],Integer> replicationScope,
HRegionInfo hri,
org.apache.hadoop.hbase.shaded.protobuf.generated.WALProtos.BulkLoadDescriptor desc,
