HI iam using solr 4.7.1 and trying to do a full import.My data source is a table in mysql. It has 10000000 rows and 20 columns.
Whenever iam trying to do a full import solr stops responding. But when i try to do a import with a limit of 400000 or less it works fine. If i try to import more than this solr wont index the result it either stops responding or will show "indexing failed". In the error log it says "Unable to execute query".But i dont understand how is the query running fine for lesser number of records but fails when i run more number of records My system config are follows CPU-i7 Ram -6Gb OS-64 bit windows 7 I am not able to figure out what the problem is ,i have tried increasing the max_allowed_packet to 1000M and even java heap size. please help thanks in advance *This is the error code* `Exception while processing: playername document : SolrInputDocument(fields: []):org.apache.solr.handler.dataimport.DataImportHandlerException: Unable to execute query: SELECT player_id,firstname,lastname,value1,value2,value3,value4,value5,value6, value7,value8,value9,value10, value11,value18,value19,value20, country_id, playername_modtime,player_flag from playername WHERE 'true' != 'false' OR playername.playername_modtime > '2014-05-23 10:38:56' Processing Document # 1 at org.apache.solr.handler.dataimport.DataImportHandlerException.wrapAndThrow(DataImportHandlerException.java:71) at org.apache.solr.handler.dataimport.JdbcDataSource$ResultSetIterator.(JdbcDataSource.java:281) at org.apache.solr.handler.dataimport.JdbcDataSource.getData(JdbcDataSource.java:238) at org.apache.solr.handler.dataimport.JdbcDataSource.getData(JdbcDataSource.java:42) at org.apache.solr.handler.dataimport.SqlEntityProcessor.initQuery(SqlEntityProcessor.java:59) at org.apache.solr.handler.dataimport.SqlEntityProcessor.nextRow(SqlEntityProcessor.java:73) at org.apache.solr.handler.dataimport.EntityProcessorWrapper.nextRow(EntityProcessorWrapper.java:243) at org.apache.solr.handler.dataimport.DocBuilder.buildDocument(DocBuilder.java:477) at org.apache.solr.handler.dataimport.DocBuilder.buildDocument(DocBuilder.java:416) at org.apache.solr.handler.dataimport.DocBuilder.doFullDump(DocBuilder.java:331) at org.apache.solr.handler.dataimport.DocBuilder.execute(DocBuilder.java:239) at org.apache.solr.handler.dataimport.DataImporter.doFullImport(DataImporter.java:411) at org.apache.solr.handler.dataimport.DataImporter.runCmd(DataImporter.java:483) at org.apache.solr.handler.dataimport.DataImporter$1.run(DataImporter.java:464) Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet successfully received from the server was 130,037 milliseconds ago.
