Support skewed join in pig -------------------------- Key: PIG-792 URL: https://issues.apache.org/jira/browse/PIG-792 Project: Pig Issue Type: Improvement Reporter: Sriranjan Manjunath
Fragmented replicated join has a few limitations: - One of the tables needs to be loaded into memory - Join is limited to two tables Skewed join partitions the table and joins the records in the reduce phase. It computes a histogram of the key space to account for skewing in the input records. Further, it adjusts the number of reducers depending on the key distribution. We need to implement the skewed join in pig. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
