deardeng opened a new pull request, #61087:
URL: https://github.com/apache/doris/pull/61087
Cause:
- FRONTENDS() goes through metadata scan and may be generated on master FE.
- In this path, currentConnectedFE context is not always preserved, so
CurrentConnected falls back to master and WHERE CURRENTCONNECTED='Yes' always
matches master.
Fix:
- Reuse TFrontendsMetadataParams.cluster_name as a pass-through slot to
carry the FE host that accepted the client connection from TVF planning to
metadata generation.
- Populate this host in FrontendsTableValuedFunction#getMetaScanRange
(prefer ConnectContext.currentConnectedFEIp, fallback to self host).
- Read and apply it in MetadataGenerator#frontendsMetadataResult via
FrontendsProcNode#getFrontendsInfo(env, infos, currentConnectedFeHost).
- Add comments at write/read points to explain why cluster_name is reused
for this pass-through.
Verification:
- FE UT: org.apache.doris.tablefunction.FrontendsTableValuedFunctionTest
