However, the reason to cause straggler is complicated. Previous works mostly focus on straggler detection, schedule level optimization and coarse-grained cause analysis. These methods cannot provide valuable insights to help users optimize their programs. In this paper, we propose BigRoots, a general method incorporating both framework and system features for root-cause analysis of stragglers in big data system. BigRoots considers features from big data framework such as shuffle read/write bytes and ","authors_text":"Hailong Yang, Honggang Zhou, Jie Jia, Wei Li, Yunchun Li","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DC","submitted_at":"2018-01-10T11:24:05Z","title":"BigRoots: An Effective Approach for Root-cause Analysis of Stragglers in Big Data System"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1801.03314","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:7def50b9aa30ed91e9e44c9d32cf33330f9b6c88919014280dd612aae14f2fdb","target":"record","created_at":"2026-05-18T00:26:17Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"8ff3885e7d565a06b8e933f5e411e981ce8df8f385bf57fb7169db1b49b8018c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DC","submitted_at":"2018-01-10T11:24:05Z","title_canon_sha256":"f13e3f13db8f9cf84ccc93ca6ad2be6bac2dba1ac6e402ac40cd25f2a45ce954"},"schema_version":"1.0","source":{"id":"1801.03314","kind":"arxiv","version":1}},"canonical_sha256":"1ebc19c892eb9850b9821d256acea26d361711c50d73d3884d8412a81ed6210f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1ebc19c892eb9850b9821d256acea26d361711c50d73d3884d8412a81ed6210f","first_computed_at":"2026-05-18T00:26:17.432886Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:26:17.432886Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pTN5IXlg2B9Y4b30sXkbviZNzfpJCVdWW9mPFjQts7QUKuvrEP2qKBSybuLplit0fi0R3F8Gskn3Nn9+vaT4Dw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:26:17.433464Z","signed_message":"canonical_sha256_bytes"},"source_id":"1801.03314","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7def50b9aa30ed91e9e44c9d32cf33330f9b6c88919014280dd612aae14f2fdb","sha256:55ecb93a0656affc224c4e73b4dcf190cf6457b4df784c486ddf2629dfffd59a"],"state_sha256":"cc0aa4e596c888fbd2cd806a9e59e50b29f74d58cdc9ccb8bda6659d19b3510e"}
