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]:-********

阈值分割源码matlab 用于新型腹部数据集的皮肤分割的深度学习技术 介绍 该存储库提供了[]中研究的皮肤分割方法的代码，主要是Mask-RCNN，U-Net，全连接网络和用于阈值化的MATLAB脚本。 该算法主要是为了使用RGB图像对创伤患者进行腹部皮肤分割而开发的，这是正在进行的研究工作的一部分，该研究工作旨在开发用于创伤评估的自主机器人[] []。 机器人腹部超声系统具有摄像头查看的腹部区域，以及相应的分段式皮肤面罩。 腹部皮肤数据集的信息 该数据集包含从Google图像搜索在线检索的1,400幅腹部图像，这些图像随后进行了手动分段。 选择图像以保留不同种族的多样性，从而防止分割算法中的间接种族偏见； 700张图像代表肤色较深的人，其中包括非洲，印度和西班牙裔群体，而700张图像代表肤色较浅的人，例如高加索人和亚洲裔群体。 总共选择了400张图像来代表体重指数较高的人，在明亮和黑暗类别之间平均分配。 在数据集准备中，还考虑了个人之间的差异，例如头发和纹身的覆盖范围，以及阴影等外部差异。 图片尺寸为227x227像素。 皮肤像素占整个像素数据的66％，每个单个图像的平均值为54.4

commons-collections-3.2.1，

windows版Redis-x64-3.2.100.msi 和 linux版的，网上很难下载windows版的，所以下载上传了

commons fileupload-1.2.1 ，很有用的java，留着用的到。

用此版本可以量产sandisk cruzer micro Skin CZ4，就是那个外面包着透明橡胶的U盘。本人4G的亲测成功，不保证更大容量可以用，手上没货，没机会测试。 注意：最好备份资料，格式化后再量产。 简要方法(量产过程实在简单)： 1.BIN 里面放U3CUSTOM.iso(你可以把现成的iso镜像改成U3CUSTOM.iso放进去。) 2.U3CUSTOM 里面放需要制作成镜像的文件（这个很自由，想放什么就放什么进去,然后双击ISOCreate.cmd，系统就会提取你在U3CUSTOM里放的文件，打包成U3CUSTOM.iso镜像放到BIN里面去了）。 3.执行　Universal_Customizer.exe　是量产主程序。没什么好说的，上面的做完后，打开Universal_Customizer.exe，基本就是NEXT了。 4.写入的速度可能有点慢,要有耐心,大概到55%的时候就刷的一下完成了。中途不可拨出U盘，否则……你试试就知道后果了！ 5.按照上面说的做，保证成功率很高，祝你好运！ 6.量产后想重新量产最好执行“U3Uninstall.exe”删除CD后再量产。
