我指下面給出的Cloudera的搜索索引文件 -如何在索引Solr中的數據時解決MAX_ARRAY_LENGTH錯誤?
https://www.cloudera.com/documentation/enterprise/5-9-x/topics/search_data_index_prepare.html https://www.cloudera.com/documentation/enterprise/5-9-x/topics/search_batch_index_use_mapreduce.html
我已經準備集合和模式文件和文件morphline按照我的數據集,則在csv格式。
id jobtitle jobdescription city state classification salary
1 Senior Android Developer complex problem solving New Hope PA it 94036
2 Mobile Solutions Developer complex problem solving Glen Allen VA it 60726
我使用的MRIT命令是:
sudo -u hdfs hadoop \
--config /etc/hadoop/conf.cloudera.yarn \
jar /opt/cloudera/parcels/CDH/lib/solr/contrib/mr/search-mr-*-job.jar
org.apache.solr.hadoop.MapReduceIndexerTool \
-D 'mapred.child.java.opts=-Xmx500m' \
--log4j /opt/cloudera/parcels/CDH/share/doc/search-
1.0.0+cdh5.8.3+0/examples/solr-nrt/log4j.properties \
--morphline-file $HOME/jobs.conf \
--output-dir NN:8020/user/$USER/outdir \
--zk-host localhost/solr --collection jobs\
--go-live \
NN:8020/user/$USER/indir
下面是我的架構文件 -
<?xml version="1.0" encoding="UTF-8" ?>
<schema name="example" version="1.5">
<fields>
<!-- Posts -->
<field name="id" type="string" indexed="true" stored="true"
required="true"/>
<field name="jobtitle" type="text_general" indexed="true"

我做了幹運行,它的工作,但與上線我總是得到MAX_ARRAY_LENGTH錯誤。
1554 [main] INFO org.apache.solr.hadoop.MapReduceIndexerTool - Indexing 1
files using 1 real mappers into 2 reducers
Error: MAX_ARRAY_LENGTH
該錯誤似乎在映射階段。
1686 [main] ERROR org.apache.hadoop.mapred.YarnChild - Error running child
: java.lang.NoSuchFieldError: MAX_ARRAY_LENGTH
at org.apache.lucene.codecs.memory.DirectDocValuesFormat.<clinit>
(DirectDocValuesFormat.java:58)
請幫我解決這個問題。
