Hi Junjie,
If you can’t load the classes, I’m not sure what’s going on. You should be
able to use --jars and --driver-class-path to add the Jar on the command
line. Try that, and also make sure you’re using a recent Jar built from
master because we renamed from com.netflix a little while ago.
Right now, master only supports reading from HDFS tables in Spark. That
looks like this:
val df = spark.read.format("iceberg").load("hdfs://...")
df.createOrReplaceTempView("table_name")
We’re working on getting better support into Spark with the DataSourceV2
effort. CTAS was just committed, and we will have a PR for reading v2
tables from SQL posted to Spark shortly.
I’m also planning on updating the Spark code so that it can use a Hive
metastore for tables now that we have committed the connection pool in
iceberg-hive.
