I am trying to load/write the data from Redis cache in my spark-sql java based application.
Here is my code:
SparkSession sprk = SparkSession.builder().appName("Bulk processing").master("local").config("spark.redis.host", "127.0.0.1")
.config("spark.redis.port", "57855").getOrCreate();
Dataset<Row> employeeDF = sprk.read().format("org.apache.spark.sql.redis").
option("table","employees").load();
employeeDF.show();
This is the exception I am getting:

The code is below:
// Configure Spring session listener.
cacheCfg.setCacheStoreSessionListenerFactories(new Factory<CacheStoreSessionListener>() {
#Override public CacheStoreSessionListener create() {
CacheSpringStoreSessionListener lsnr = new CacheSpringStoreSessionListener();
lsnr.setDataSource(JdbcConnectionPool.create("jdbc:mysql://localhost:3306/platform75",
"root", "root"));
return lsnr;
}
});
In case you're trying to load data from MySQL to Ignite, you need to have MySQL driver on classpath. Just put the driver JAR into IGNITE_HOME/libs folder prior to starting the nodes, and rerun data loading.

Does anybody knows how to resolve this problem?
I was getting a BLOB which using this line of code:
InputStream binaryStream = rs.getBlob(i).getBinaryStream();
I change it to this line of code:
InputStream test = rs.getBinaryStream(i);
and I was not getting this exception again.
Maybe this was not the problem, but for me it works.

The connection looks like this:
connection = DriverManager.getConnection(
"jdbc:jtds:sybase://127.0.0.1:2631/serverName", "DBA",
"password");
I had heard that this may ocurre do to the driver, but i get the same error when I am using jconn3.

So, this is an odd one. c3p0 doesn't Proxy CLOBs. Somehow the CLOB that you've gotten has been wrapped behind a Java standard dynamic proxy. You'll need to figure out how that happened. Where did your proxied CLOB object come from?
It looks as though hibernate sometimes proxies CLOBs, see ClobProxy. Maybe this is why you have a proxy rather than the sort of CLOB your driver expects?
