----------------------------------
Summary: 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] "
