Example 1 with Row

use of org.apache.hadoop.hive.llap.Row in project hive by apache.

the class TestJdbcWithMiniLlap method processQuery.

private int processQuery(String query, int numSplits, RowProcessor rowProcessor) throws Exception {
    String url = miniHS2.getJdbcURL();

    job.set(LlapBaseInputFormat.USER_KEY, user);
    job.set(LlapBaseInputFormat.PWD_KEY, pwd);
    job.set(LlapBaseInputFormat.QUERY_KEY, query);
    InputSplit[] splits = inputFormat.getSplits(job, numSplits);
    assertTrue(splits.length > 0);
