复现过程2：
1. bm在release 0.11.3上生成数据
同上
2. 0.11.3 cli修改时间序列，增加tag信息
alter timeseries root.group_0.d_0.s_2 UPSERT ALIAS=alias_s2 TAGS(tag='hi')
ATTRIBUTES(attr1='money')
flush
3.copy 0.11.3的data到rel 0.11.4
java程序测试用例：
import org.apache.iotdb.rpc.IoTDBConnectionException;
import org.apache.iotdb.rpc.StatementExecutionException;
import org.apache.iotdb.session.SessionDataSet.DataIterator;
import org.apache.iotdb.session.pool.SessionDataSetWrapper;
import org.apache.iotdb.session.pool.SessionPool;
import org.apache.iotdb.tsfile.file.metadata.enums.TSDataType;
import org.apache.iotdb.session.SessionDataSet;
import org.apache.iotdb.session.Session;
import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
public class SessionPoolExample {
private static SessionPool pool;
private static ExecutorService service;
private static Session session;
public static void main(String[] args)
throws StatementExecutionException, IoTDBConnectionException,
InterruptedException {
pool = new SessionPool("127.0.0.1", 6667, "root", "root", 3);
service = Executors.newFixedThreadPool(10);
session = new Session("127.0.0.1", 6667, "root", "root");
session.open(false);
query();
Thread.sleep(1000);
pool.close();
session.close();
service.shutdown();
}
private static void query() throws IoTDBConnectionException,
StatementExecutionException {
SessionDataSet dataSet;
String sql = "ALTER timeseries root.group_0.d_0.s_2 UPSERT
ALIAS=alias_test
TAGS(tag='test',dir='/data/test',exName='exTest',description='desTest',unit='unitTest')
ATTRIBUTES(minValue=1,maxValue=1000)";
pool.executeNonQueryStatement(sql);
dataSet = session.executeQueryStatement("show timeseries where
tag='test'");
System.out.println(dataSet.getColumnNames());
dataSet.setFetchSize(1024); // default is 10000
while (dataSet.hasNext()) {
System.out.println(dataSet.next());
}
dataSet.closeOperationHandle();
}
}
编译，运行：
javac -cp
/data/lz/pr_test/rel_12/distribution/target/apache-iotdb-0.12.1-SNAPSHOT-server-bin/apache-iotdb-0.12.1-SNAPSHOT-server-bin/lib/*:.
./SessionPoolExample.java
java -cp
/data/lz/pr_test/rel_12/distribution/target/apache-iotdb-0.12.1-SNAPSHOT-server-bin/apache-iotdb-0.12.1-SNAPSHOT-server-bin/lib/*:.
