----------------------------------------
Summary: Float type coercion with hiveContext
Key: SPARK-8840
URL: https://issues.apache.org/jira/browse/SPARK-8840
Project: Spark
Issue Type: Bug
Components: SparkR
Affects Versions: 1.4.0
Reporter: Evgeny SInelnikov
Problem with +float+ type coercion on SparkR with hiveContext.
{code}
> result <- sql(hiveContext, "SELECT offset, percentage from data limit 100")
> show(result)
DataFrame[offset:float, percentage:float]
> head(result)
Error in as.data.frame.default(x[[i]], optional = TRUE) :
cannot coerce class ""jobj"" to a data.frame
{code}
This trouble looks like already exists (SPARK-2863 - Emulate Hive type
coercion in native reimplementations of Hive functions) with same
reason - not completed "native reimplementations of Hive..." not
"...functions" only.
I used spark 1.4.0 binaries from official site:
http://spark.apache.org/downloads.html
And running it on:
* Hortonworks HDP 2.2.0.0-2041
* with Hive 0.14
* with disabled hooks for Application Timeline Servers (ATSHook) in
hive-site.xml, commented:
** hive.exec.failure.hooks,
** hive.exec.post.hooks,
** hive.exec.pre.hooks.
