Log Context

Log”{} Can’t calculate hash from blob for file [{}] [{}]” classname is BlobStoreRepository.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                                 // to ensure we don't double the space in the repo since old snapshots
                                // don't have this hash we try to read that hash from the blob store
                                // in a bwc compatible way.
                                maybeRecalculateMetadataHash(blobContainer; fileInfo; metadata);
                            } catch (Exception e) {
                                logger.warn(() -> new ParameterizedMessage("{} Can't calculate hash from blob for file [{}] [{}]";
                                    shardId; fileInfo.physicalName(); fileInfo.metadata()); e);
                            }
                            if (fileInfo.isSame(md) && snapshotFileExistsInBlobs(fileInfo; blobs)) {
                                // a commit point file with the same name; size and checksum was already copied to repository
                                // we will reuse it for this snapshot
