Duo Zhang created HBASE-27775:
---------------------------------
Summary: TestMultiSlaveReplication fails when using table based
replication queue storage
Key: HBASE-27775
URL: https://issues.apache.org/jira/browse/HBASE-27775
Project: HBase
Issue Type: Sub-task
Components: Replication
Reporter: Duo Zhang
Assignee: Duo Zhang
The tests uses a small wal rolling size for testing more operations
{code}
// smaller block size and capacity to trigger more operations
// and test them
conf1.setInt("hbase.regionserver.hlog.blocksize", 1024 * 20);
conf1.setInt("replication.source.size.capacity", 1024);
{code}
But after moving to table based replication queue storage, the update to
hbase:replication tablr will also be append to the same WAL file, so it will
make the replicaton worker move forward, and then it will update the
hbase:replication table since the offset has been changed, so then it will make
the replication work again, and so on...
This will make the wal file size reach the configured size easily and trigger
unexpected wal rolling, and then fail the test.
For fixing the test, we can increase the wal rolling size, or we can use multi
wal, to separate the wal files of hbase:replication table along. so it will not
mess up the normal wal files.
