### Apache Iceberg version
0.14.0
### Query engine
Spark
### Please describe the bug 🐞
I use SparkActions.rewriteDataFiles to compact my small files, this is my
code
String namespace = "dwm_stk";
SparkSession sparkSession = SparkSession.builder()
.config("spark.sql.extensions",
"org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions")
.config("spark.sql.catalog.spark_catalog",
"org.apache.iceberg.spark.SparkSessionCatalog")
.config("spark.sql.catalog.spark_catalog.type", "hive")
.config("spark.sql.catalog.local",
"org.apache.iceberg.spark.SparkCatalog")
.config("spark.sql.catalog.local.type", "hadoop")
.config("spark.sql.catalog.local.warehouse",
"$PWD/warehouse")
.config("iceberg.engine.hive.enabled", "true")
.config("spark.sql.autoBroadcastJoinThreshold", "-1")
.config("spark.shuffle.service.enabled", "true")
.config("spark.dynamicAllocation.enabled", "true")
.config("spark.dynamicAllocation.initialExecutors", "1")
.config("spark.dynamicAllocation.maxExecutors", "10")
.config("spark.shuffle.service.port", "7337")
.config("spark.sql.adaptive.enabled", "true")
.config("spark.python.authenticate.socketTimeout", "120s")
.enableHiveSupport()
.getOrCreate();
HiveCatalog catalog = new HiveCatalog();
catalog.setConf(sparkSession.sparkContext().hadoopConfiguration());
Map<String, String> properties = new HashMap<>();
catalog.initialize("hive", properties);
SparkActions sparkActions = SparkActions.get(sparkSession);
String[] tables = new String[]{
"mt_bigbuyorder", "mt_bigsellorder",
"mt_bigtotalorder",
"mt_bigwillingbuyorder", "mt_bigwillingsellorder",
"mt_bigwillingtotalorder", "mt_buyorder",
"mt_min_bigbuyorder",
"mt_min_bigsellorder", "mt_min_bigtotalorder",
"mt_min_bigwillingbuyorder",
"mt_min_bigwillingsellorder", "mt_min_bigwillingtotalorder",
"mt_min_buyorder",
"mt_min_sellorder", "mt_min_totalorder",
"mt_min_willingbuyorder",
"mt_min_willingsellorder", "mt_min_willingtotalorder",
"mt_sellorder",
"mt_totalorder", "mt_willingbuyorder",
"mt_willingsellorder", "mt_willingtotalorder"
};
for (String tableString : tables) {
Table table = catalog.loadTable(TableIdentifier.of(namespace,
tableString));
long tsToDelete = System.currentTimeMillis();
sparkActions.deleteOrphanFiles(table).olderThan(tsToDelete).execute();
sparkActions.rewriteDataFiles(table)
.option("target-file-size-bytes", Long.toString(128 *
1024 * 1024)) // 128 MB
.option("max-concurrent-file-group-rewrites", "20")
.option("delete-file-threshold", "1")
.execute();
long tsToExpire = System.currentTimeMillis();
sparkActions
.expireSnapshots(table)
.expireOlderThan(tsToExpire)
.execute();
}
my question is my rewriteDataFiles task would stuck when it have finished
1.5k job, with all the spark worker down and driver process cost high cpu over
to 98% cpu of my server even I can't use jstack <pid> to get the driver's
threaddump.
I doubt that may be an endless loop bug in SparkActions.rewriteDataFiles.
please help me fix it, thanks
