             Summary: BeelineHiveClient can't parse Hive meta data result set with partitioned table
                 Key: KYLIN-3969
                 URL: https://issues.apache.org/jira/browse/KYLIN-3969
             Project: Kylin
          Issue Type: Bug
          Components: Metadata
    Affects Versions: v2.6.1
         Environment: Hive 3.1.0, HiveServer2, Beeline（Along with Ambari 2.7.1.0)
CentOS Linux release 7.6.1810
            Reporter: Tuo Zhu


When creating a model, you can add tables without partitions, but can't add ones with partitions.
 Web UI pops："Oops. cannot get HiveTableMeta".
 I tried same table in Hive2 with cli, it works.

log prints:
{code:java}
 java.lang.RuntimeException: cannot get HiveTableMeta

 at org.apache.kylin.source.hive.HiveMetadataExplorer.loadTableMetadata(HiveMetadataExplorer.java:66){code}
 

After checking the code, I believe the reason is here in /src/main/java/org/apache/kylin/source/hive/BeelineHiveClient.java:

 
{code:java}
// code placeholder
private void parseResultEntry(ResultSet resultSet, HiveTableMetaBuilder builder) throws  SQLException{
        List<HiveTableMeta.HiveTableColumnMeta> partitionColumns = Lists.newArrayList();
        if ("# Partition Information".equals(resultSet.getString(1).trim())) {
            resultSet.next();
            Preconditions.checkArgument("# col_name".equals(resultSet.getString(1).trim()));
            resultSet.next();
            Preconditions.checkArgument("".equals(resultSet.getString(1).trim()));
            while (resultSet.next()) {
                if ("".equals(resultSet.getString(1).trim())) {
                    break;
                }
                partitionColumns.add(new HiveTableMeta.HiveTableColumnMeta(resultSet.getString(1).trim(),
                        resultSet.getString(2).trim(), resultSet.getString(3).trim()));
            }
            builder.setPartitionColumns(partitionColumns);
        }
{code}
 

 

The code here expects a blank line in "# Partition Information" section after "# col_name" line, in "desc formatted tablename" output, which does exist in Hive 2, CLI mode:
{quote}# Partition Information
# col_name data_type comment

pt string
{quote}
But in Hive3, Beeline client, it outputs:
{quote}| # Partition Information | NULL        | NULL        |
| # col_name                  | data_type | comment  |
| pt                                  | string        |                  |
{quote}
The blank line is gone, which makes folloing line fails. 
{code:java}
Preconditions.checkArgument("".equals(resultSet.getString(1).trim()));{code}
