Goun Na commented on SPARK-19131:
---------------------------------
I can reproduce it when "if exists" is omitted.
{code}
sql("alter table t drop partition (p=1)")
{code}
> Support "alter table drop partition [if exists]"
> ------------------------------------------------
>
> Key: SPARK-19131
> URL: https://issues.apache.org/jira/browse/SPARK-19131
> Project: Spark
> Issue Type: New Feature
> Affects Versions: 2.1.0
> Reporter: lichenglin
>
> {code}
> val parts = client.getPartitions(hiveTable, s.asJava).asScala
> if (parts.isEmpty && !ignoreIfNotExists) {
> throw new AnalysisException(
> s"No partition is dropped. One partition spec '$s' does not exist
> in table '$table' " +
> s"database '$db'")
> }
> parts.map(_.getValues)
> {code}
> Until 2.1.0,drop partition will throw a exception when no partition to drop.
> I notice there is a param named ignoreIfNotExists.
> But I don't know how to set it.
> May be we can implement "alter table drop partition [if exists] "
