Package org.apache.hadoop.hbase.replication.regionserver

Class TestWALEntryStreamCompressionReset

java.lang.Object

org.apache.hadoop.hbase.replication.regionserver.TestWALEntryStreamCompressionReset

public class TestWALEntryStreamCompressionReset
extends Object

Enable compression and reset the WALEntryStream while reading in ReplicationSourceWALReader.

This is used to confirm that we can work well when hitting EOFException in the middle when reading a WAL entry, when compression is enabled. See HBASE-27621 for more details.
