Nishant Kelkar commented on HIVE-9557: -------------------------------------- Figured out the issue. Made a dummy var. HADOOP_HOME point to HIVE_HOME. Also, removed commented out queries from the udf_cosine_similarity.q clientpositive file. I'll upload a patch with an RB link soon. > create UDF to measure strings similarity using Cosine Similarity algo > --------------------------------------------------------------------- > > Key: HIVE-9557 > URL: https://issues.apache.org/jira/browse/HIVE-9557 > Project: Hive > Issue Type: Improvement > Components: UDF > Reporter: Alexander Pivovarov > Assignee: Nishant Kelkar > Labels: CosineSimilarity, SimilarityMetric, UDF > Attachments: udf_cosine_similarity-v01.patch > > > algo description http://en.wikipedia.org/wiki/Cosine_similarity > {code} > --one word different, total 2 words > str_sim_cosine('Test String1', 'Test String2') = (2 - 1) / 2 = 0.5f > {code} > reference implementation: > https://github.com/Simmetrics/simmetrics/blob/master/src/uk/ac/shef/wit/simmetrics/similaritymetrics/CosineSimilarity.java -- This message was sent by Atlassian JIRA (v6.3.4#6332)
