hive installation deployment, there are many tutorials on the web, I will not repeat here, this time I would like to talk about how hive submits the HQL statement to hive execution. There are several ways: first, hiveserver provide thrift interface by building Hiveserver to receive HQL statement execution from remote commit. The benefit of this is that there i

Hive has been used for a while, but no related logs have been written, because hive is mainly used in the create table, upload data, and crud processes. Later, I needed some frequently used methods in my work. I learned that hive supports UDF (user define function). I have read some articles and found that UDF writing is also very simple, inherit the UDF and over

Recently, I am working on a learning-type remote control. According to the initial design, I have added the hs0038 Integrated Receiver to identify the two formats of RC5 NEC. Later, it was found that the better method was waveform replication and analysis. Because the integrated receiving header could not measure the carrier, it could not be used as a learning remote control for complete waveform replication. Looking for information, we can see that

value is true and can receive broadcasts.0x03 ready to achieve:0x001 when generating a priority in the SDK, the receivers required to check for push:Static checks to see if the corresponding component can be found, if no component is found (including no receiver at all, note that there is no component found, not "found component, just false"), the direct return priority is 0, otherwise the default check passes, The priority generation algorithm is ge

Previously, the original author's code was further encapsulated by using the template class to automatically implement the COM connection point receiver (Sink), and the principle used by the connection point was clarified. During the process of viewing the ATL code, it is found that ATL itself provides a mechanism such as AtlAdvise/AtlUnadvise to simplify the use of connection points. In CComPtrBase, Advise is also a member function, which further enc

In the process of using a serial port to send data, it is found that the program will not execute the contents of the main function after first entering the serial port, and the content of the interrupt is not executed. Query a large number of data found that: the serial port in receiving too much data, there will be serial port overflow error, and enter the overflow interrupt (ore interrupt). Next comes the cause of the error and the workaround.(1) What is ore interrupt. Why is it produced. The

If join key is equal, it is written to HDFs.The map join is called a map join because all of its work is computed on the map side.Hive has made several optimizations on the map join:In hive 0.6, the default is that a large table is behind a select, a small table in front, or a/*+mapjoin (map_table) */hint to set it. In hive 0.7, this calculation

When you have a need to do all kinds of statistics from a hive table, then fall into the statistical tables of each category to store. Naturally we would think of using the Hive Multi Insert statement to implement it. Because you can avoid multiple scans of the same original table data by using the Multi Insert statement.
