Get Qubole data row wise using java

Question

Am trying to run a hive query using Qubole SDK. Though am able to get the desired result as string, in order to better process it, am looking to access this row-wise. Something like a list of java objects.

The way am getting the data is:

CommandResponse commandResponse = client.command().hive().query(query).invoke().get();
ResultLatch resultLatch = new ResultLatch(client, commandResponse.getId());
ResultValue resultValue = resultLatch.awaitResult();
System.out.println(resultValue.getResults());

And the console gives an output like:

"val1"  "val2"  "val3"  "val4"
........ some more set of values .......

I was looking to have this result set in the form of list which I can iterate over instead of parsing or tokenizing the bunch of strings.

Unable to find any library or class if its there.

Split string by \r\n first, then by \t like this:

import org.apache.commons.lang3.StringUtils;

...

private static String convertNulls(String s) {
    \\Use this function to convert blanks, null and \\N to''
    return StringUtils.isBlank(s) | 
       s.equalsIgnoreCase("null") | 
        s.equalsIgnoreCase("\\N") ? "" : s;
}

...

inputStr=resultValue.getResults();

if (!StringUtils.isBlank(inputStr)) {
            for (String row: inputStr.split("\r\n")) { //split rows
                String[] s = row.split("\t");          //split columns

                //Do what you want here with s 
                //Use convertNulls method to convert all NULLs variations to empty strings
                //Or load some ArrayList or Map, etc


            }
