Simon Zhou commented on CASSANDRA-14200:
----------------------------------------
Btw, I can reproduce the same issue with trunk and the same sstable. That
indicates the issue is not fixed yet in trunk but we just need to figure out
how we ended up with a null timestamp column.

> We have an sstable whose schema has a column of type timestamp and it's not
> part of primary key. When dumping the sstable using sstabledump there is NPE
> like this:
> {code:java}

> The reason is that we use a null Date when there is no value for this column:
> {code}
> public Date deserialize(ByteBuffer bytes)
> {
> return bytes.remaining() == 0 ? null : new
> Date(ByteBufferUtil.toLong(bytes));
> }
> {code}
> It seems that we should not deserialize columns with null values.
