Subject [jira] [Updated] (HBASE-8147) Add Integration Test for "The HCat Scenario"
Date Tue, 19 Mar 2013 22:05:15 GMT

     [ https://issues.apache.org/jira/browse/HBASE-8147?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Nick Dimiduk updated HBASE-8147:
--------------------------------

    Attachment: HBASE-8147-WIP.patch

I've replicated the behavior of HCat under this scenario, but it looks like there's a problem
with the way I'm attaching dependency jars in the test. Running the HCat code against patched
HBase does not produce this error message. Attached is a WIP patch that introduces an integration
test for the above ticket. It depends on first applying the trunk patch attached to that ticket.

To run locally, apply the two patches, set up a pseudo-distributed cluster, and launch the
job with:

{noformat}
$ HADOOP_CLASSPATH=$(./bin/hbase classpath) hadoop \
  jar hbase-it/target/hbase-it-0.97-SNAPSHOT-tests.jar \
  org.apache.hadoop.hbase.mapreduce.IntegrationTestImportTsv
