             Summary: Enhancement while getting partitions via webhcat client
                 Key: HIVE-7762
                 URL: https://issues.apache.org/jira/browse/HIVE-7762
             Project: Hive
          Issue Type: Improvement
          Components: WebHCat
            Reporter: Suhas Vasu
            Priority: Minor


Hcatalog creates partitions in lower case, whereas getting partitions from 
hcatalog via webhcat client doesn't handle this. So the client starts throwing 
exceptions.
Ex:
CREATE EXTERNAL TABLE in_table (word STRING, cnt INT) PARTITIONED BY (Year 
STRING, Month STRING, Date STRING, Hour STRING, Minute STRING) STORED AS 
TEXTFILE LOCATION '/user/suhas/hcat-data/in/';

Then i try to get partitions by:
{noformat}
        String inputTableName = "in_table";
        String database = "default";

        Map<String, String> partitionSpec = new HashMap<String, String>();
        partitionSpec.put("Year", "2014");
        partitionSpec.put("Month", "08");
        partitionSpec.put("Date", "11");
        partitionSpec.put("Hour", "00");
        partitionSpec.put("Minute", "00");

        HCatClient client = get(catalogUrl);
        HCatPartition hCatPartition = client.getPartition(database, 
inputTableName, partitionSpec);
{noformat}

This throws up saying:
{noformat}
Exception in thread "main" org.apache.hcatalog.common.HCatException : 9001 : 
Exception occurred while processing HCat request : Invalid partition-key 
specified: year

{noformat}

The same code works if i do
{noformat}
        partitionSpec.put("year", "2014");
        partitionSpec.put("month", "08");
        partitionSpec.put("date", "11");
        partitionSpec.put("hour", "00");
        partitionSpec.put("minute", "00");
{noformat}
