> Summary
> We had been chasing a WAL corruption issue reported on one of our customers
> deployments running release 2.1.1 (CDH 6.1.0). After providing a custom
> modified jar with the extra sanity checks implemented by HBASE-21401 applied
> on some code points, plus additional debugging messages, we believe it is
> related to DirectByteBuffer usage, and Unsafe copy from offheap memory to
> on-heap array triggered
> [here|https://github.com/apache/hbase/blob/branch-2.1/hbase-common/src/main/java/org/apache/hadoop/hbase/util/ByteBufferUtils.java#L1157],
> such as when writing into a non ByteBufferWriter type, as done
> [here|https://github.com/apache/hbase/blob/branch-2.1/hbase-common/src/main/java/org/apache/hadoop/hbase/io/ByteBufferWriterOutputStream.java#L84].
