This must be a newbie question but I’ve tried just about everything found from google search and from the documentation but to no avail. When trying to put index in HDFS, my attempt to create cores always fail with "no segments* file found in HdfsDirectory"
For example: ~/solr-5.2.1/server/solr/configsets> solr create_core -c robert -d hdfs_basic Creating new core 'robert' using command: http://localhost:8983/solr/admin/cores?action=CREATE&name=robert&instanceDir=robert Failed to create core 'robert' due to: Error CREATEing SolrCore 'robert': Unable to create core [robert] Caused by: no segments* file found in HdfsDirectory@dafcec5f lockFactory=org.apache.solr.store.hdfs.HdfsLockFactory@5e3b9ecc: files: [write.lock] In configsets/hdfs_basic/conf/solrconfig.xml I have the following: <directoryFactory name="DirectoryFactory" class="solr.HdfsDirectoryFactory"> <str name="solr.hdfs.home">hdfs://wrnidphmn0002:9000/user/tzz2c94/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> <lockType>hdfs</lockType> I've tested that the command is indeed reading this config file by the crude test of putting in a bad classname and seeing the appropriate error message. I've also tried the alternative command line method, solr start -Dsolr.directoryFactory=HdfsDirectoryFactory -Dsolr.lock.type=hdfs -Dsolr.hdfs.home=hdfs://wrnidphmn0002:9000/user/tzz2c94/solr and with solr start -Dsolr.directoryFactory=HdfsDirectoryFactory -Dsolr.lock.type=hdfs -Dsolr.data.dir=hdfs://wrnidphmn0002:9000/user/tzz2c94/solr/data -Dsolr.updatelog=hdfs://wrnidphmn0002:9000/user/$USER/solr/upd I've also tried using cloud mode and from suggestions found from a google search, setting unlockOnStartup but neither helped. I'm out of things to try. Can anybody help? Nothing in this message is intended to constitute an electronic signature unless a specific statement to the contrary is included in this message.
