[jira] [Commented] (GORA-476) Nutch 2.X GeneratorJob creates
NullPointerException when using DataFileAvroStore
[ https://issues.apache.org/jira/browse/GORA-476?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16299254#comment-16299254 ]
Lewis John McGibbney commented on GORA-476:
-------------------------------------------
Example gora.properties
{code}
gora.avrostore.codec.type=JSON
gora.avrostore.input.path=file:///usr/local/nutch/runtime/local/gora.datafileavrostore.inject.output
gora.avrostore.output.path=file:///usr/local/nutch/runtime/local/gora.datafileavrostore.generate.output
gora.datastore.default=org.apache.gora.avro.store.DataFileAvroStore
{code}
This assumes that inject job output has already been written to {code}file:///usr/local/nutch/runtime/local/gora.datafileavrostore.inject.output{code}
