Hi all,
 
&nbsp;
 
Discussion around 3.0.1 seems to have trickled away.&nbsp; What was blocking 
the release process kicking off?&nbsp; I can see some unresolved bugs raised 
against 3.0.0, but conversely there were quite a few  critical correctness 
fixes waiting to be released.
 
&nbsp;
 
Cheers,
 
Jason.

&gt; Just wanted to check if there are any blockers that we are still waiting 
for to start the new release process.
 
 
I don't see any on-going blocker in my area.
  
Thanks for the notification.

Hi, Yi.
  
&nbsp;
 
  
Could you explain why you think that is a blocker? For the given example from 
the JIRA description,
 
  
&nbsp;
 
 
 
     spark.udf.register("key", udf((m: Map[String, String]) =&gt; 
m.keys.head.toInt)) 
 
 
    Seq(Map("1" -&gt; "one", "2" -&gt; 
"two")).toDF("a").createOrReplaceTempView("t") 
 
 
    checkAnswer(sql("SELECT key(a) AS k FROM t GROUP BY key(a)"), Row(1) :: 
Nil) 
 
 
     
&nbsp;
 
  
Apache Spark 3.0.0 seems to work like the following.
 
  
&nbsp;
 
 
 
      
scala&gt; spark.version
 
 
 
 
     
res0: String = 3.0.0
 
 
 
 
     
&nbsp;
 
 
 
 
     
scala&gt; spark.udf.register("key", udf((m: Map[String, String]) =&gt; 
m.keys.head.toInt))
 
 
 
 
     
res1: org.apache.spark.sql.expressions.UserDefinedFunction = 
SparkUserDefinedFunction($Lambda$1958/948653928@5d6bed7b,IntegerType,List(Some(class[value[0]:
 map<string,string&gt;])),None,false,true)
 
 
 
 
     
&nbsp;
 
 
 
 
     
scala&gt; Seq(Map("1" -&gt; "one", "2" -&gt; 
"two")).toDF("a").createOrReplaceTempView("t")
 
 
 
 
     
&nbsp;
 
 
 
 
     
scala&gt; sql("SELECT key(a) AS k FROM t GROUP BY key(a)").collect
 
 
 
 
     
res3: Array[org.apache.spark.sql.Row] = Array([1])
 
 
 
 
     
&nbsp;
 
  
Could you provide a reproducible example?
 
  
&nbsp;
 
  
Bests,
 
  
Dongjoon.
