HI i am trying to get data from Solr server .
This is my code
/*input is JavaRDD<SolrDocumentList> li
*output is JavaRDD<Get> for scanning Hbase*/
public static JavaRDD<Get> getdocs(JavaRDD<SolrDocumentList> li)
{
JavaRDD<SolrDocumentList> newdocs=li;
JavaRDD<Get> n=newdocs.map(new Function<SolrDocumentList,Get>(){
public Get call(SolrDocumentList si) throws IOException
{
Get get = null;
for (SolrDocument doc : si) {
get = new Get(Bytes.toBytes(((String)
doc.getFieldValue("id"))));
}
return get;
}
}
issue am getting below error
