Question

使用JDBC API在hive中执行插入查询。但查询未运行。有人可以建议出了什么问题。另外，请告诉我如何捕获hive在运行查询时抛出的错误代码。 Hive版本0.13.0

当我在命令行中运行日志中生成的查询时，它们正常工作。

public static void onSuccess() {
        // Write to log on Success
        LOGGER.info("Job Succeeded, Updating the " + hiveDB + "." + logTable + " with status SUCCESS");
        String insertOnSuccess = "insert into table " + hiveDB + "." + logTable + " select " + currentJobID + "," + "'"
                + startTime + "'" + "," + "'" + stopTime + "'" + "," + runTime + "," + "\'SUCCESS\' from " + hiveDB
                + "." + "dual" + " limit 1; ";
        commonDB.InsertToTable(insertOnSuccess);
        JobMailer.PostMail("IB Load Successfully completed", "Load completed");

    }


public void InsertToTable(String insertquery) {
        try {

            stm = hiveConn.createStatement();
            stm.executeUpdate(insertquery);
        } catch (SQLException e) {
            LOGGER.error("Running the insert query for :" + insertquery);
        } catch (Exception e) {
            LOGGER.error(e.getMessage());
        } finally {
            if (stm != null) {
                try {
                    stm.close();
                } catch (SQLException e) {
                    LOGGER.error(e.getMessage());
                    ;
                }
            }
        }
    }

这是我的错误日志：

太糟糕了，你被Hive 0.13困住了，因为......

从Hive 0.14.0开始，HiveServer2操作日志可用为直线客户。 https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Clients#HiveServer2Clients-HiveServer2Logging

在服务器端激活日志调度后，您可以从Java代码中检索这些日志条目 - 异步或整体执行结束时，使用类似...... < / p>

  private static void DumpHiveMessages (java.sql.Statement stmtGeneric)
  { org.apache.hive.jdbc.HiveStatement stmtExtended ;
    try
    { stmtExtended =(org.apache.hive.jdbc.HiveStatement)stmtGeneric ;
      for (String sLogMessage : stmtExtended.getQueryLog())
      { JustTraceIt("HIVE SAYS>" +sLogMessage) ;    } 
      if (stmtExtended.hasMoreLogs())
      { JustTraceIt("WARNING>(...log stream still open...") ; }
    }
    catch (Exception duh)
    { JustTraceIt("WARNING>Error while accessing Hive log stream");
      JustTraceIt("WARNING>" +MakeSenseOfDirtyHadoopException(duh)) ;
    }
  }

那些东西没有真正记录，但是有源代码，例如 http://grepcode.com/file/repo1.maven.org/maven2/org.apache.hive/hive-jdbc/0.14.0/org/apache/hive/jdbc/HiveStatement.java

我认为Hive插入/更新/删除功能仍有一些问题是hive 1.2.1。但你好像仍然在蜂巢0.14。所以我不建议使用这些功能。请查看其他用户发生的类似问题：
