Examples with HashJoinPlan org.apache.phoenix.execute.HashJoinPlan used on opensource projects

Example 1 with HashJoinPlan

use of org.apache.phoenix.execute.HashJoinPlan in project phoenix by apache.

the class QueryCompilerTest method testSaltTableJoin.

@Test
public void testSaltTableJoin() throws Exception {
    PhoenixConnection conn = (PhoenixConnection) DriverManager.getConnection(getUrl());
    try {
        conn.createStatement().execute("drop table if exists SALT_TEST2900");

        conn.createStatement().execute("create table RIGHT_TEST2900" + "(" + "appId VARCHAR not null primary key," + "createTime VARCHAR" + ")");
        String sql = "select * from SALT_TEST2900 a inner join RIGHT_TEST2900 b on a.appId=b.appId where a.id>=3 and a.id<=5";
        HashJoinPlan plan = (HashJoinPlan) getQueryPlan(sql, Collections.emptyList());
        ScanRanges ranges = plan.getContext().getScanRanges();
        List<HRegionLocation> regionLocations = conn.getQueryServices().getAllTableRegions(Bytes.toBytes("SALT_TEST2900"));
