--------------------------------
Summary: Bound the executePutBlockClose retry in
BlockDataStreamOutput
Key: HDDS-16265
URL: https://issues.apache.org/jira/browse/HDDS-16265
Project: Apache Ozone
Issue Type: Improvement
Components: Ozone Client
Reporter: Ren Koike
Assignee: Ren Koike
BlockDataStreamOutput.executePutBlock() has an unbounded recursive retry in the
close path: if executePutBlockClose fails, the whenComplete callback calls
executePutBlock(true, false) recursively with no limit. On persistent failure
this can stack overflow or loop indefinitely.
Fix: replace unbounded recursion with a bounded retry or fail-fast. The
executePutBlockClose is a compatibility mechanism (HDDS-12007 made datanodes
ignore this putBlock), so failure is non-critical — the regular putBlockAsync
handles the actual commit.
Verification: existing unit tests pass, plus a new test for the
close-retry-exhaustion scenario.
