USB HID（Human Interface Device）2.1调试工具是一款专为开发者设计的专业软件，它主要用于测试和调试基于USB接口的HID类设备。HID设备通常包括键盘、鼠标、游戏控制器等，但也可以是自定义的硬件设备，这些设备通过USB接口与计算机通信，发送和接收数据。 USB HID规范是USB设备类定义的一部分，它定义了如何在USB系统中使用人机交互设备。版本2.1是对早期版本的更新，增加了更多功能和改进，以适应不断发展的硬件需求。这款调试工具就是针对这一标准的，帮助开发者确保他们的设备能够正确地按照HID 2.1规范工作。 该软件的核心功能包括： 1. **数据收发**：允许用户发送和接收数据到HID设备，这对于测试设备的输入和输出功能至关重要。通过模拟用户操作，开发者可以验证设备是否能正确解析和响应来自主机的命令。 2. **Set Report**：此功能允许设置设备的状态或配置。HID设备通过报告来传递信息，Set Report指令用于向设备发送控制信息，改变设备的内部状态或配置。 3. **Set Feature**：这是另一个控制传输，用于设置设备的特性。这可能包括设备的工作模式、电源管理设置等，开发者可以通过这个功能调整设备的各种参数。 4. **Get Report**：这个功能用于从设备获取当前状态或数据报告。它可以帮助开发者了解设备的实时反馈，以检查其运行情况。 5. **用户友好的界面**：工具的易用性是其一大亮点。直观的界面使得即使没有深厚技术背景的用户也能进行基本的调试工作，简化了设备开发过程。 在实际应用中，USB HID 2.1调试工具通常用于以下几个步骤： - 设备识别：检查电脑是否能正确识别和枚举HID设备。 - 报告描述符验证：分析设备发送的报告描述符，确保它们符合HID规范。 - 功能测试：通过Set和Get Report命令测试设备的所有功能。 - 错误检测：寻找并修复设备在数据交换过程中的任何错误。 `usb_hid_debug_tool.exe`是这个调试工具的可执行文件，用户只需运行此文件即可启动调试过程。在使用时，确保设备已连接到电脑，并正确安装了相应的驱动程序，这样调试工具才能正常工作。 USB HID 2.1调试工具是开发和调试自定义HID设备的关键工具，它简化了与USB HID设备的交互过程，使得开发者可以快速定位问题，优化设备性能，提升产品的稳定性和兼容性。对于任何涉及到USB HID设备的项目，这款软件都是不可或缺的辅助工具。

greenplum-db-6.2.1-rhel7-x86_64.rpm Pivotal Greenplum 6.2 Release Notes This document contains pertinent release information about Pivotal Greenplum Database 6.2 releases. For previous versions of the release notes for Greenplum Database, go to Pivotal Greenplum Database Documentation. For information about Greenplum Database end of life, see Pivotal Greenplum Database end of life policy. Pivotal Greenplum 6 software is available for download from the Pivotal Greenplum page on Pivotal Network. Pivotal Greenplum 6 is based on the open source Greenplum Database project code. Important: Pivotal Support does not provide support for open source versions of Greenplum Database. Only Pivotal Greenplum Database is supported by Pivotal Support. Release 6.2.1 Release Date: 2019-12-12 Pivotal Greenplum 6.2.1 is a minor release that includes new features and resolves several issues. New Features Greenplum Database 6.2.1 includes these new features: Greenplum Database supports materialized views. Materialized views are similar to views. A materialized view enables you to save a frequently used or complex query, then access the query results in a SELECT statement as if they were a table. Materialized views persist the query results in a table-like form. Materialized view data cannot be directly updated. To refresh the materialized view data, use the REFRESH MATERIALIZED VIEW command. See Creating and Managing Materialized Views. Note: Known Issues and Limitations describes a limitation of materialized view support in Greenplum 6.2.1. The gpinitsystem utility supports the --ignore-warnings option. The option controls the value returned by gpinitsystem when warnings or an error occurs. If you specify this option, gpinitsystem returns 0 if warnings occurred during system initialization, and returns a non-zero value if a fatal error occurs. If this option is not specified, gpinitsystem returns 1 if initialization completes with warnings, and returns value of 2 or greater if a fatal error occurs. PXF version 5.10.0 is included, which introduces several new and changed features and bug fixes. See PXF Version 5.10.0 below. PXF Version 5.10.0 PXF 5.10.0 includes the following new and changed features: PXF has improved its performance when reading a large number of files from HDFS or an object store. PXF bundles newer tomcat and jackson libraries. The PXF JDBC Connector now supports pushdown of OR and NOT logical filter operators when specified in a JDBC named query or in an external table query filter condition. PXF supports writing Avro-format data to Hadoop and object stores. Refer to Reading and Writing HDFS Avro Data for more information about this feature. PXF is now certified with Hadoop 2.x and 3.1.x and Hive Server 2.x and 3.1, and bundles new and upgraded Hadoop libraries to support these versions. PXF supports Kerberos authentication to Hive Server 2.x and 3.1.x. PXF supports per-server user impersonation configuration. PXF supports concurrent access to multiple Kerberized Hadoop clusters. In previous releases of Greenplum Database, PXF supported accessing a single Hadoop cluster secured with Kerberos, and this Hadoop cluster must have been configured as the default PXF server. PXF introduces a new template file, pxf-site.xml, to specify the Kerberos and impersonation property settings for a Hadoop or JDBC server configuration. Refer to About Kerberos and User Impersonation Configuration (pxf-site.xml) for more information about this file. PXF now supports connecting to Hadoop with a configurable Hadoop user identity. PXF previously supported only proxy access to Hadoop via the gpadmin Greenplum user. PXF version 5.10.0 deprecates the following configuration properties. Note: These property settings continue to work. The PXF_USER_IMPERSONATION, PXF_PRINCIPAL, and PXF_KEYTAB settings in the pxf-env.sh file. You can use the pxf-site.xml file to configure Kerberos and impersonation settings for your new Hadoop server configurations. The pxf.impersonation.jdbc property setting in the jdbc-site.xml file. You can use the pxf.service.user.impersonation property to configure user impersonation for a new JDBC server configuration. Note: If you have previously configured a PXF JDBC server to access Kerberos-secured Hive, you must upgrade the server definition. See Upgrading PXF in Greenplum 6.x for more information. Changed Features Greenplum Database 6.2.1 includes these changed features: Greenplum Stream Server version 1.3.1 is included in the Greenplum distribution. Resolved Issues Pivotal Greenplum 6.2.1 is a minor release that resolves these issues: 29454 - gpstart During Greenplum Database start up, the gpstart utility did not report when a segment instance failed to start. The utility always displayed 0 skipped segment starts. This issue has been resolved. gpstart output was also enhanced to provide additional warnings and summary information about the number of skipped segments. For example: [WARNING]:-********
