yui2010 opened a new pull request #30522:
URL: https://github.com/apache/spark/pull/30522
### What changes were proposed in this pull request?
1. add setSparkConf method in SparkContext
2.set the newest sparkconf in SparkContext#getOrCreate
### Why are the changes needed?
reproduce as follow code:
SparkConf sparkConf = new SparkConf().setAppName("hello");
sparkConf.set("spark.master", "local");
JavaSparkContext jssc = new JavaSparkContext(sparkConf);
spark = SparkSession.builder()
.config("spark.serializer",
"org.apache.spark.serializer.KryoSerializer")
.config("hive.exec.dynamici.partition",
true).config("hive.exec.dynamic.partition.mode", "nonstrict")
.config("hive.metastore.uris", "thrift://hivemetastore:9083")
.enableHiveSupport()
.master("local")
.getOrCreate();
spark.sql("select * from hudi_db.hudi_test_order").show();
it will produce follow Exception AssertionError: assertion failed: No
plan for HiveTableRelation [`hudi_db`.`hudi_test_order` … (at current master
branch)
org.apache.spark.sql.AnalysisException: Table or view not found:
`hudi_db`.`hudi_test_order`; (at spark v2.4.4)
The reason is SparkContext#getOrCreate(SparkConf) will return activeContext
that include previous spark config if it has
but the input SparkConf is the newest which include previous spark config
and options.
enableHiveSupport will set options (“spark.sql.catalogImplementation",
"hive”) when spark session created it will miss this conf
SharedState load conf from sparkContext and will miss hive catalog
