Sasha Ovsankin commented on SPARK-14927:
----------------------------------------
Seems that the workaround is not to let saveAsTable create the table but rather
create it oneself prior to writing to it, like so:
{code}
hc.sql("create external table tmp.partitiontest1(val string) partitioned by
(year int)")
Seq(2012 -> "a", 2013 -> "b", 2014 -> "c").toDF("year", "val")
.write
.partitionBy("year")
.mode(SaveMode.Append)
.saveAsTable("tmp.partitiontest1")
{code}
> DataFrame. saveAsTable creates RDD partitions but not Hive partitions

> Key: SPARK-14927
> URL: https://issues.apache.org/jira/browse/SPARK-14927
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.5.2, 1.6.1
> Environment: Mac OS X 10.11.4 local
> Reporter: Sasha Ovsankin
>
> This is a followup to
> http://stackoverflow.com/questions/31341498/save-spark-dataframe-as-dynamic-partitioned-table-in-hive
> . I tried to use suggestions in the answers but couldn't make it to work in
> Spark 1.6.1
> I am trying to create partitions programmatically from `DataFrame. Here is
> the relevant code (adapted from a Spark test):
> hc.setConf("hive.metastore.warehouse.dir", "tmp/tests")
> // hc.setConf("hive.exec.dynamic.partition", "true")
> // hc.setConf("hive.exec.dynamic.partition.mode", "nonstrict")
> hc.sql("create database if not exists tmp")
> hc.sql("drop table if exists tmp.partitiontest1")
> Seq(2012 -> "a").toDF("year", "val")
> .write
> .partitionBy("year")
> .mode(SaveMode.Append)
> .saveAsTable("tmp.partitiontest1")
> hc.sql("show partitions tmp.partitiontest1").show
> Full file is here:
> https://gist.github.com/SashaOv/7c65f03a51c7e8f9c9e018cd42aa4c4a
> I get the error that the table is not partitioned:
> ======================
> HIVE FAILURE OUTPUT
> ======================
> SET hive.support.sql11.reserved.keywords=false
> SET hive.metastore.warehouse.dir=tmp/tests
> OK
> OK
> FAILED: Execution Error, return code 1 from
> org.apache.hadoop.hive.ql.exec.DDLTask. Table tmp.partitiontest1 is not a
> partitioned table
> ======================
> It looks like the root cause is that
> `org.apache.spark.sql.hive.HiveMetastoreCatalog.newSparkSQLSpecificMetastoreTable`
> always creates table with empty partitions.
> Any help to move this forward is appreciated.
