Hi,
A fellow forum member kindly spotted a lousy error of mine, where a comma was
missing at the line above the red line.
This appears to be accepted
spark = SparkSession.builder \
.appName("app1") \
.enableHiveSupport() \
.getOrCreate()
# Hive settings
settings = [
("hive.exec.dynamic.partition", "true"),
("hive.exec.dynamic.partition.mode", "nonstrict"),
("spark.sql.orc.filterPushdown", "true"),
("hive.msck.path.validation", "ignore"),
("spark.sql.caseSensitive", "true"),
("spark.speculation", "false"),
("hive.metastore.authorization.storage.checks", "false"),
("hive.metastore.client.connect.retry.delay", "5s"),
("hive.metastore.client.socket.timeout", "1800s"),
("hive.metastore.connect.retries", "12"),
("hive.metastore.execute.setugi", "false"),
("hive.metastore.failure.retries", "12"),
("hive.metastore.schema.verification", "false"),
("hive.metastore.schema.verification.record.version", "false"),
("hive.metastore.server.max.threads", "100000"),
("hive.metastore.authorization.storage.checks", "/apps/hive/warehouse"),
("hive.stats.autogather", "true")
]
spark.sparkContext._conf.setAll(settings)However, I have not tested it myself.

I am afraid not supported for spark sql

I tried it as below
spark = SparkSession.builder \
.appName("app1") \
.enableHiveSupport() \
.getOrCreate()
# Hive settings
settings = [

("hive.stats.autogather", "true")
]
spark.sparkContext._conf.setAll(settings)
got this error

`spark.sql.statistics.size.autoUpdate.enabled` is only work for table stats
update.But for partition stats,I can only update it with `ANALYZE TABLE
tablename PARTITION(part) COMPUTE STATISTICS`.So is Spark SQL able to auto
update partition stats like hive by setting hive.stats.autogather=true?
