Review comment:
@wuchong ,hi , i check the code, when deserializeToObject called, there
could be a same problem. But when i dig deeper, It seems ok.
There're two place where `deserializeToObject` is called.
One(I think it's ok) is like the following in
`HBaseReadWriteHelper.parseToRow(Result result, Object rowKey`):
```java
if (value != null) {
familyRow.setField(q, HBaseTypeUtils.deserializeToObject(value,
typeIdx, charset));
} else {
familyRow.setField(q, null);
}
```
The other one also looks good (in `HBaseReadWriteHelper.parseToRow(Result
result)`) :
```java
public Row parseToRow(Result result) {
if (rowKeyIndex == -1) {
return parseToRow(result, null);
} else {
Object rowkey =
HBaseTypeUtils.deserializeToObject(result.getRow(), rowKeyType, charset);
return parseToRow(result, rowkey);
}
}
```
I can't think of a scenario that result.getRow could return a null value
because this code is used to parse the returned value form hbase with a scan
command.
Do you have any suggestion?
