--------------------------------
Assignee: Takuya Ueshin
> DataFrame can't execute after uncacheTable.
> -------------------------------------------
>
> Key: SPARK-15870
> URL: https://issues.apache.org/jira/browse/SPARK-15870
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Takuya Ueshin
> Assignee: Takuya Ueshin
> Fix For: 2.0.0
>
>
> If a cached {{DataFrame}} executed more than once and then do
> {{uncacheTable}} like the following:
> {code}
> val selectStar = sql("SELECT * FROM testData WHERE key = 1")
> selectStar.createOrReplaceTempView("selectStar")
> spark.catalog.cacheTable("selectStar")
> checkAnswer(
> selectStar,
> Seq(Row(1, "1")))
> spark.catalog.uncacheTable("selectStar")
> checkAnswer(
> selectStar,
> Seq(Row(1, "1")))
> {code}
> , the uncached {{DataFrame}} can't execute because of {{Task not
> serializable}} exception like:
> {noformat}
> org.apache.spark.SparkException: Task not serializable
