This call populates the {{OutputJobInfo}} with details fetched from the Metastore. > # {{HCatOutputFormat.setSchema()}} to indicate the output-schema for the data being written. > It is a common mistake to invoke {{HCatOUtputFormat.setSchema()}} as follows: > {code:java} > HCatOutputFormat.setSchema(conf, HCatOutputFormat.getTableSchema(conf)); > {code} > Unfortunately, {{getTableSchema()}} returns only the record-schema, not the entire table's schema. We'll need a better API for use in M/R jobs to get the complete table-schema. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
