“INSERT INTO …” with SparkSQL HiveContext

Question

I'm trying to run an insert statement with my HiveContext, like this:

hiveContext.sql('insert into my_table (id, score) values (1, 10)')

The 1.5.2 Spark SQL Documentation doesn't explicitly state whether this is supported or not, although it does support "dynamic partition insertion".

This leads to a stack trace like

AnalysisException:
Unsupported language features in query: insert into my_table (id, score) values (1, 10)
TOK_QUERY 0, 0,20, 0
  TOK_FROM 0, -1,20, 0

      TOK_SELEXPR 0, -1,-1, 0
        TOK_ALLCOLREF 0, -1,-1, 0

Is there any other way to insert to a Hive table that is supported?

Answer 1

In order to insert the data to a Hive table I would suggest you to use the append mode on the DataFrameWriter.

data = hc.sql("select 1 as id, 10 as score")

data.write.mode("append").saveAsTable("my_table")
