This commit implements comprehensive changes to align the project with Apache Software Foundation incubation requirements and complete the migration from Greenplum to Apache Cloudberry branding. - Add DISCLAIMER file as required for Apache incubating projects - Update LICENSE file with comprehensive list of 245 files containing Apache License headers, organized by module (FDW, External Table, Server, Documentation, CI/Test templates) - Add Apache License headers to GitHub workflow files - Update CONTRIBUTING.md with Apache project contribution guidelines - Update README.md with Apache Cloudberry branding and simplified content - Update documentation templates in docs/content/ to use Cloudberry - Update automation and testing documentation - Migrate server scripts and Java components references - Update CI/CD workflows with proper Apache licensing - Clean up legacy CI documentation (remove ci/README.md) - Update build system references in Makefile - Enhance installation scripts to support both Cloudberry 2.0 and 2.1+ - Add transition guide for Cloudberry migration - Update all user-facing documentation with correct branding - Simplify README.md focusing on essential information - Update book configuration for documentation generation This change ensures full compliance with Apache incubation requirements while completing the transition to Apache Cloudberry ecosystem.
Main changes are included: * Rename package from pxf-gpX to cloudberry-pxf * Update installation paths to /usr/local/cloudberry-pxf-[VERSION] * Remove legacy pxf-gp7.spec and pxf-cbdb1.spec files * Update DEBIAN package control files with new naming * Standardize package configuration based on cloudberry-pxf.spec
### hbase-client update
Update `hbase-client` from `1.3.2` to `2.3.7` (latest version with minimal 3rd-party library updates) with following decision made:
* Use hadoop 2 version - Despite of the fact that we are using hadoop 3 in automation tests, we still using hadoop2 libs for all other connectors.
* Use shaded version of libraries when it relocates java-packages to new namespaces
* Use non-shaded version of libraries when it just bundles several jars to single fat-jar. Fat jars hides dependencies from gradle, however puts classes on classpath. This will lead to unpredictable issues.
Fortunately, `hbase-client:2.3.7` depends on `hadoop-2.10.0` that we are using! No changes here.

### Other changes
* Automation tests: upgrade hbase to 2.3.7
Update the name format from `cloudberry-pxf-*` to `apache-cloudberry-pxf-incubating` for the deb/rpm files.
### Useful changes in Parquet 1.12.x -> 1.15.x * Support LZ4_RAW codec * Implement vectored IO in Parquet file format * More optimal memory usage in compression codecs Dependency tree changes are small: ``` +--- org.apache.parquet:parquet-column:1.15.1 | +--- org.apache.parquet:parquet-common:1.15.1 | | +--- org.apache.parquet:parquet-format-structures:1.15.1 | +--- org.apache.parquet:parquet-encoding:1.15.1 | | +--- org.apache.parquet:parquet-common:1.15.1 (*) +--- org.apache.parquet:parquet-hadoop:1.15.1 | +--- org.apache.parquet:parquet-column:1.15.1 (*) | +--- org.apache.parquet:parquet-format-structures:1.15.1 (*) | +--- org.apache.parquet:parquet-common:1.15.1 (*) | +--- org.xerial.snappy:snappy-java:1.1.10.7 | +--- io.airlift:aircompressor:2.0.2 | +--- commons-pool:commons-pool:1.6 | +--- com.github.luben:zstd-jni:1.5.6-6 +--- org.apache.parquet:parquet-jackson:1.15.1 +--- org.apache.parquet:parquet-generator:1.15.1 +--- org.apache.parquet:parquet-pig:1.15.1 | +--- org.apache.parquet:parquet-column:1.15.1 (*) | +--- org.apache.parquet:parquet-hadoop:1.15.1 (*) | +--- org.apache.parquet:parquet-common:1.15.1 (*) \--- org.apache.parquet:parquet-format:2.10.0 ``` It has its own thrift library shaded. It doesn't depend on protobuf. `parquet-hadoop` in fact expects that there is `hadoop-client`, `hadoop-common`, `hadoop-annotations` and `hadoop-mapreduce-client-core` provided.
