ECFileChecksumHelper#getChunkInfos
copies the original EC pipeline and limits nodes to specific replicas. However, the list of "nodes in order", used for topology-aware read, still contains all original nodes. Thus it may happen that read is attempted from the wrong node.This patch updates "nodes in order" in the copy to reflect the same set of nodes as the unordered one.
Also remove a stray placeholder from the error message:
Fail to get block checksum for ... checksum combine mode : {}COMPOSITE_CRC
https://issues.apache.org/jira/browse/HDDS-8276
How was this patch tested?
Updated the integration test
TestOzoneFileChecksum
to cover both topology-aware and regular read.https://github.com/adoroszlai/hadoop-ozone/actions/runs/4553955626
