Subject [jira] [Updated] (CRUNCH-552) Enable AvroParquet to work with Crunch-on-Spark
Date Tue, 28 Jul 2015 00:39:04 GMT

     [ https://issues.apache.org/jira/browse/CRUNCH-552?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Josh Wills updated CRUNCH-552:
------------------------------
    Attachment: CRUNCH-552.patch

The patch for this, which does a couple of things:

1) Makes Crunch's custom OutputFormat for Parquet public so Spark can access it,
2) Moves some of the avro test classes (Employee and Person) to the crunch-test module so
that they can be used by both crunch-core and crunch-spark,
3) Adds Avro/Parquet tests for Spark, and
4) Notes that crunch.namedoutput should be set to "out0" in Crunch-on-Spark so that the Avro
Parquet implementation will work properly.

> Via the mailing list, we got a bug report that Crunch's Parquet target classes did not
work with Crunch-on-Spark. The most obvious problem was Spark not being able to access the
OutputFormat class that Crunch was using for reading Parquet files as Avro records, but there
were a couple of other smaller issues that needed to be fixed as well.
