Hello All -
Am new to ElasticSearch (and Lucene based searching) but was trying to use the BulkIndexer from Java.
I went about it in the following steps:
1. Creating a TransportClient (to localhost).
2. Creating indexes dynamically based on a set of directory names (where pdf docs are).
3. Creating a Map of Map\ where String is name of file and Object is the InputStream to the file.
* * *
* * *
## Then I call BulkIndexer: (where esClient is a TransportClient). brb = esClient.prepareBulk(); FileComposer fileComposer = new FileComposer(); Map\\> documentMap = fileComposer.getDocumentsToIndex(fileList\_); if (documentMap.size() \> 0) { for (String docUUID: documentMap.keySet()) { docUUID = UUID.randomUUID().toString(); brb.add(esClient.prepareIndex(indexName, docUUID).setSource(XContentFactory.jsonBuilder().map(documentMap.get(docUUID)))); } brb.execute().actionGet(); }
* * *
Everything works fine - no errors. I have log messages as it goes through each directory and catch exceptions. However when I look at the log I get the following errors.
Please note: At log messages I log whether an index exists or not as per error generated when new index by dirname is attempted to be created and such.
## My indexnames (from dirnames) are in the following format: 'lang.java', 'lang.scala' etc. Is the indexname an issue by anychance? It creates indexes fine (as long as lowercase) and goes through status updates but here are the errors I get:
