[PR] build(thirdparty): make RocksDB depend on Hadoop before building HDFS plugin [incubator-pegasus]

["empiredan (via GitHub)" <gi...@apache.org>]

empiredan opened a new pull request, #2412:
URL: https://github.com/apache/incubator-pegasus/pull/2412

   Add an explicit thirdparty build dependency from RocksDB to Hadoop.
   
   RocksDB builds the HDFS plugin on Linux, and that plugin includes hdfs.h from the
   Hadoop native client output. Without a CMake ExternalProject dependency, RocksDB
   and Hadoop can build in parallel, causing RocksDB to compile before Hadoop has copied
   hdfs.h into thirdparty/output/include/hdfs.
   
   This fixes intermittent thirdparty Docker build failures such as:
     fatal error: hdfs.h: No such file or directory
   
   Validation:
   - Verified the failure is caused by RocksDB HDFS plugin compiling before Hadoop native client output is available.
   - The change serializes RocksDB after Hadoop while preserving existing thirdparty build behavior.
