readJsonTweets Morphline using the MapReduceIndexerTool Results in No Documents in Solr

shaileshCG — Fri, 16 Sep 2022 10:08:33 GMT

I am using the MapReduceIndexerTool to index some Tweets with the Morphline readJsonTweets.conf and the job completes successfully but no documents are created in Solr Search. With Log4J set to TRACE I can see the Twitter data parsed successfully against the schema.xml defined. I would welcome any help as to why no index data is stored.

Thanks

Shailesh

Hi Shailesh, Are you using the --go-live option on the IndexerTool? Mike

Yes, this the command line I run:

Do you have access to the task logs for your Indexer job?

Can you confirm that you are seeing lines that look like the following (the numbers and dates will likely be different)?

2016-03-06 17:09:07,953 INFO [main] org.apache.solr.hadoop.SolrRecordWriter: docsWritten: 20

2016-03-06 17:09:13,984 INFO [main] org.apache.solr.hadoop.SolrRecordWriter: docsWritten: 880

Are there any errors that you are seeing in the map or reduce task attempt logs?

I have docsWritten = 0 on Reducer log below but I don't know why. Btw I am trying this with a single tweet at the moment.

Re: readJsonTweets Morphline using the MapReduceIndexerTool Results in No Documents in Solr

mdrob — Sat, 12 Mar 2016 13:30:29 GMT

How did you generate the morphline file?

Have you had a chance to look at our tutorials? Specifically, http://www.cloudera.com/documentation/enterprise/latest/topics/search_batch_index_use_mapreduce.html gives an example morphline file -- can you compare?

Also, you can try running with --dry-run to get faster test executions and better debug what is going on.

Re: readJsonTweets Morphline using the MapReduceIndexerTool Results in No Documents in Solr

shaileshCG — Sat, 12 Mar 2016 19:54:04 GMT

I used the tutorial to set up the activity of using the MRIT. I used the example readJsonTweets.conf provided with the examples on CDH 5.6:

morphlines : [
  {
    id : morphline1
    importCommands : ["org.kitesdk.**", "org.apache.solr.**"]

    commands : [
      {
        readJsonTestTweets {
          isLengthDelimited : false
        }
      }
      { logDebug { format : "output record: {}", args : ["@{}"] } }
    ]
  }
]

The only thing that is missing is the SOLR_LOCATOR which I specify on MapReduceIndexerTool command line. Does that make a difference?

Looking at the Reducer logs I see the following error which refers to collection1 which I don't have in any of my SolrCores. Does this imply Zookeeper config corruption? I also tried but failed to initialise Solr config in ZooKeeper using CM Solr Initialise, solrctl init --force and zookeeper-client rmr /solr. But non have successfully supported the initialisation process for Solr. Also removed the usercache on all the NodeManager/DataNode nodes but this didn't cure the problem.

Re: readJsonTweets Morphline using the MapReduceIndexerTool Results in No Documents in Solr

whosch — Sun, 13 Mar 2016 21:15:41 GMT

Looks like you are missing a loadSolr command in your morphline, for example as shown here: see http://www.cloudera.com/documentation/enterprise/latest/topics/search_batch_index_use_mapreduce.html?scroll=csug_topic_4_3

(FYI, with MapReduceIndexerTool the SOLR_LOCATOR is substituted from whatever is specified on the CLI with --zk-host option)

Excellent that solved the problem along with some unknown fields in the schema.xml where I have now used sanitizeUnknownSolrFields in the Morphline . Thanks for your help.
