sorting - How to implement Sort Merge Bucketing Map Join? -

-

I would like to join two tables that have the same number of buckets with the same columns and the same sort.

Apart from that setting, do you need to set up any other status other than setting the properties? 

  set hive Ooptimize.bucketmapjoin = true; Set hive Optimimize.biketmapjoin.re sortedmerge = true; Set hive.input.format = org.apache.hadoop.hive.ql.io.BucketizedHiveInputFormat;    
 
 
 If you have two datasets that are too large to join in the map side To include a skilled person, the technique is to sort two datasets into buckets.  
 This trick is cluster and sorts by joining it. 
 table order (int, price float, quantity int) CLUSTERED BY CREDIT (CID) in 32 wallet;  
 Make Table Clients (ID Fav, First String, Last String) in CLUSTERED BY 32 Bucket;  
 This provides two major optimization benefits:  
 Adding to  makes it easy to trim, the value of all possible matches remains on the same area on the disk. All the values ​​matching a bucket are tied on the same node, there can be no shuffle after joining in equality.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
