Eric C. Ho
Eric C. Ho's work was selected for the XERJ Corpus Hub, the open reference memory AI coding agents search before they write code. When an agent meets the same problem, it gets this implementation back as a worked example, with the author and the repository attached.
Totals across every corpus @echonesis appears in; a commit selected for two corpora counts once. Files and lines count the selected commits; each corpus indexes the whole repository at its pinned commit.
What an agent can do with the ozone corpus
apache/ozone: Scalable, reliable, distributed storage system optimized for data analytics and object store workloads
- Look up how ozone implements hadoop, object-store, storage, with answers cited to file and line.
- Reuse a worked example: the commit “HDDS-16247. Separate StorageContainerLocationProtocol RPC identity fr…” (39 files · Java).
- Answer from ozone's real Java source instead of memory (Operations and SRE).
- How does ozone implement hadoop?
- What does hadoop-hdds do in ozone?
Search the GitHub repository apache/ozone with XERJ (https://hub.xerj.org/corpus/apache--ozone). Run these in a shell, in order, and check each result before the next: 1. xerj --help (success: it prints usage). If xerj is missing: curl -fsSL https://xerj.org/get | sh 2. git clone https://github.com/apache/ozone ozone && git -C ozone checkout 4f853ccf48434335978ec21865ec9d6b1c178cdc 3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data 4. xerj autoindex ./ozone --url http://127.0.0.1:9200 --prefix ozone --progress plain 5. xerj autoindex map --url http://127.0.0.1:9200 Then answer my question from the indexed files and cite the ax_path of every hit.

The corpus is the whole repository at the pinned commit, not only the files of the selected commit.
Not installable yet: this corpus is not in the hub registry until its licence review passes, so xerj corpus add and xerj ask cannot fetch it. It becomes installable when this card says live in the hub.
Sign in with GitHub or Hugging Face to see more: every selected commit in full (commit date, every folder, licence review state, pin) and the pack builds of each corpus.
