-----------------------------------
Summary: HCat reader/writer doc needs a discussion of failure cases
Key: HCATALOG-478
URL: https://issues.apache.org/jira/browse/HCATALOG-478
Project: HCatalog
Issue Type: Bug
Components: documentation
Affects Versions: 0.5
Reporter: Alan Gates
Assignee: Lefty Leverenz
Priority: Minor
>From HCATALOG-444
Something that's not clear in the doc is how write failures are handled. For
example, are output written to a staging directory, then moved into place? Can
a worker task that crashes during writes restart and rewrite the data without
getting duplicates? Is there a "commit" or "close" type operation to signal all
writers have completed writing?
