Zhihong Yu commented on HBASE-5699:
-----------------------------------
Currently we maintain one sequence number per region per HLog. From append():
{code}
this.lastSeqWritten.putIfAbsent(regionInfo.getEncodedNameAsBytes(),
Long.valueOf(seqNum));
{code}
If WALEdit's from a particular region can spread across multiple streams,
accounting would be more complex.
> Run with > 1 WAL in HRegionServer
