I change the close method of writer to :
```scala
def close() {
Option(htable) match {
case Some(t) => {
try {
t.close()
} catch {
case ex: Exception => logWarning("Close HBase table failed.", ex)
}
}
case None => logWarning("HBase table variable is null!")
}
}
```
And add the assumption to the scala document:
```
/**
* Save [[org.apache.spark.rdd.RDD[Text]]] as a HBase table
*
* The format of record in RDD should looks like this:
* rowkey|delimiter|column|delimiter|column|delimiter|...
* For example (if delimiter is ","):
* 0001,apple,banana
* "0001" is rowkey field while "apple" and "banana" are column fields.
```
