[HBASE-30195](https://issues.apache.org/jira/browse/HBASE-30195) | *Major* | **Update Thrift gateway to use new hbase-shaded-thrift in thirdparty** + +The HBase Thrift gateway no longer depends on upstream libthrift. The Thrift runtime is now provided by org.apache.hbase.thirdparty:hbase-shaded-thrift, shipped in hbase-thirdparty 4.1.14 or later. Decoupling from upstream libthrift lets HBase stay current with Thrift CVE fixes on its own cadence and preserves 2.5.x/2.6.x Java 8 compatibility regardless of upstream libthrift's evolving requirements. As part of this change the Thrift runtime is upgraded from 0.14.1 to 0.23.0. Generated Ja [...] + +Wire compatibility is preserved.
