Indexing of Spark 3 Dataframe into Apache Solr 8

NoClassDefFoundError: org/apache/solr/client/solrj/io/stream/expr/StreamExpressionParameter in Solr and Spark Livy

Spark-Solr error java.lang.ClassNotFoundException: org.apache.solr.client.solrj.io.stream.expr.StreamExpressionParameter

QUESTION

Indexing of Spark 3 Dataframe into Apache Solr 8

Asked 2021-Jun-14 at 07:42

I have setup a small size Hadoop Yarn cluster where Apache Spark is running. I have some data (JSON, CSV) that I upload to Spark (data-frame) for some analysis. Later, I have to index all data-frame data into Apache SOlr. I am using Spark 3 and Solr 8.8 version.

In my search, I have found a solution here but it is for different version of Spark. Hence, I have decided to ask someone for this.

Is there any builtin option for this task. I am open to use SolrJ and pySpark (not scal shell).

I found a solution myself. Till now Lucidword spark-solr module does not support these versions of Spark (3.0.2) and Solr (8.8). I have first installed PySolr module and then use following example code to finish my job:

I already tried to remove Solr-solrj.jar, because spark-solr contains it, but without success too.

the problem was solved as follows:

I entered all the servers that run Spark and also hdfs, looked for the solr jar that was in the spark system path (spark-solr-3.6.0.jar), as the jar was in one of Yarn's caches (/data/yarn/local/filecache or /data/yarn/local/usercache), I deleted the jar from all cache places, so it stopped showing up in spark's system path. After that, I just imported the necessary jars for Livy and it worked again. The jar looks like it was corrupted, so it was imported into Spark but the libs were not working

The solrj lib is missing in the project.

Add the solrj lib as nit should work for you.

Install spark-solr

This will build 2 jars in the target directory:. ${VERSION} will be something like 3.5.6-SNAPSHOT, for development builds. The first .jar is what you’d want to use if you were using spark-solr in your own project. The second is what you’d use to submit one of the included example apps to Spark.
spark-solr-${VERSION}.jar
spark-solr-${VERSION}-shaded.jar
