my code like this:
datasetResult.write()
.format("org.apache.spark.sql.redis")
.mode("append")
.option("table", jobDetail.getTo_table())
.option("host", jobDetail.getTo_host())
.option("port", jobDetail.getTo_port())
.option("auth", jobDetail.getTo_passwd())
.option("ttl", jobDetail.getRedis_table_ttl())
.option("key.column", "id").save();

and the code below can print:
datasetResult.show();

+---+---------+---+------------------+
| id| name|age| address|
+---+---------+---+------------------+
| 1| zhangsan| 22|fsdfsadfasdfsd|
| 2|hanmeimei| 23| bbbbccccddd|
+---+---------+---+------------------+

but when the jobDetail.getTo_host() point to a redis standalone ,it works
my dependencis:
<dependency> <groupId>com.redislabs</groupId> <artifactId>spark-redis_2.11</artifactId> <version>2.4.2</version> </dependency>

anything to help? tks
