Hi,
I am trying to setup a SolrCloud cluster on top of Hadoop cluster using
Hortonworks Data Platform. I understood how to configure Solr to enable it
to store data in HDFS (process given below). However, I could not understand
how to enable Solr to setup the cluster using Zookeeper already available
with HDP.
As per my understanding, if I make only the below HDFS related change, Solr
index data will be stored in HDFS. However, only machine from which the Solr
application is run, will act as a Solr server. Can anyone please let me know
how to configure Solr to use an external Zookeeper ensemble on HDP so that
the complete Hadoop cluster can be used as a SolrCloud cluster?
<directoryFactory name="DirectoryFactory" class="solr.HdfsDirectoryFactory">
<str name="solr.hdfs.home">hdfs://Hadoop_namenode:8020/user/solr</str>
<bool name="solr.hdfs.blockcache.enabled">true</bool>
<int name="solr.hdfs.blockcache.slab.count">1</int>
<bool name="solr.hdfs.blockcache.direct.memory.allocation">true</bool>
<int name="solr.hdfs.blockcache.blocksperbank">16384</int>
<bool name="solr.hdfs.blockcache.read.enabled">true</bool>
<bool name="solr.hdfs.blockcache.write.enabled">true</bool>
<bool name="solr.hdfs.nrtcachingdirectory.enable">true</bool>
<int name="solr.hdfs.nrtcachingdirectory.maxmergesizemb">16</int>
<int name="solr.hdfs.nrtcachingdirectory.maxcachedmb">192</int>
</directoryFactory>
Also, please let me know if there are other activities that need to be
performed to make SolrCloud working on Hadoop apart from this HDFS and
Zookeeper changes.
Thanks & Regards
Vijay
