[jira] [Created] (HIVE-11622) Creating an Avro table with a complex map-typed column leads to incorrect column type.

 Summary: Creating an Avro table with a complex map-typed column 
leads to incorrect column type.
 Key: HIVE-11622
 URL: https://issues.apache.org/jira/browse/HIVE-11622
 Project: Hive
  Issue Type: Bug
  Components: Database/Schema
Affects Versions: 1.1.0
Reporter: Alexander Behm


In the following CREATE TABLE the following map-typed column leads to the wrong 
type. I suspect some problem with inferring the Avro schema from the column 
definitions, but I am not sure.

Reproduction:
{code}
hive> create table t (c map>) stored as avro;
OK
Time taken: 0.101 seconds
hive> desc t;
OK
c   array>  from deserializer   
Time taken: 0.135 seconds, Fetched: 1 row(s)
{code}

Note how the type shown in DESCRIBE is not the type originally passed in the 
CREATE TABLE.

Don't think so, because JDBC driver has either NOSASL, KERBEROS (determined by 
the presence of principal in connection string) or password based (all others). 
I agree there is scope for improvement in how we encode that in the driver, but 
I guess we can work on it in a new jira focussed on improving that.

jdbc/src/java/org/apache/hive/jdbc/ZooKeeperHiveClientHelper.java (line 97)


(this is mostly a nit, as this perf impact would be hard to notice. but the 
tweaks are also minor) - 

The pattern can be a static final member. (It is not mutable and thread 
safe).

I think a slightly more efficient pattern would be -(add '=' to the non key 
char, that way the pattern evaluation would not have to back track after going 
beyond '=').

"([^=;]*)=([^;]*)[;]?"

(seems faster by around 20% in a quick test i did)
public class TClass {

  private static String key;
  private static String value;

  public static void main(String[] args) throws InterruptedException {
long ts = System.currentTimeMillis();

String confStr = 
"hiveserver.configparam.key1=value1;hiveserver.configparam.key2=value2;hiveserver.configparam.key3=value3;";
Pattern pattern = Pattern.compile("([^;]*)=([^;]*)[;]?");
//for (int i = 0; i < 100; i++) {
for (int i = 0; i < 1; i++) {
  Matcher matcher = pattern.matcher(confStr);

  while (matcher.find()) {
key = matcher.group(1);
value = matcher.group(2);
//System.out.println(key + ":" + value);
  }
}

System.out.println(System.currentTimeMillis() - ts);

  }

}



jdbc/src/java/org/apache/hive/jdbc/ZooKeeperHiveClientHelper.java (line 102)


The "matcher.group(1) != null" can be moved outside of each if statement to 
a common one on top.

if(matcher.group(1) == null) {
 continue;
}
If the key is not null but value is null, i think we should throw an error. 
It would indicate a bug or some corruption.

if(matcher.group(2) == null) {
 throw ..
}



jdbc/src/java/org/apache/hive/jdbc/ZooKeeperHiveClientHelper.java (line 103)


hive configuration is case sensitive, lets keep it consistent here.



service/src/java/org/apache/hive/service/server/HiveServer2.java (line 109)


typo - "initialize"



service/src/java/org/apache/hive/service/server/HiveServer2.java (line 133)


we don't seem to have any existing support for HIVE_SERVER2_AUTHENTICATION 
env variable.



service/src/java/org/apache/hive/service/server/HiveServer2.java (line 220)


Guava Joiner can be used here (it likely uses StringBuilder underneath) -
Joiner.on(';').withKeyValueSeparator("=").join(confsToPublish);



service/src/java/org/apache/hive/service/server/HiveServer2.java (line 273)


do we need to publish the password based authentication modes ?

 Summary: For GenericUDAFs, iterate function is called despite 
empty table
 Key: HIVE-11619
 URL: https://issues.apache.org/jira/browse/HIVE-11619
 Project: Hive
  Issue Type: Bug
  Components: API, Hive
 Environment: HDP 2.3
Reporter: Wei Huang



For empty input tables, the iterate function in GenericUDAF is called once with 
a null input for empty table. This makes it impossible to differentiate the 
empty table case for the case where there the table has one row with a null in 
the desired column.

This happens only when the genericUDAFcall is made with a column name specified 
and not when the '*' wild card in used.

sometime in metastore log, will get below exception,  after analysis, we found

when hivemetastore start, the DelegationTokenSecretManager will maintain the

saslServer.startDelegationTokenSecretManager(conf, *baseHandler.getMS()*,

this lead to the cocurrent issue.
