When I deleted a hive table today, I found that the HDFS space was not released. At first I thought it was a problem to delete the table. The results were not found on HDFS, the final result is that the CDH namenode has a file system spam interval setting. The default setting is one day. That is to say, it takes one day to delete the deleted file.Configuration, hoping to help people with the same questions. 650) This. width = 650; "src =" http://s3.51

International Online report (Japanese reporter Wang Yang. Zhiye xingnan said that the No. 4 nuclear power plant had a fire that morning. "A fire has occurred in the No. 4 reactor. At present, it is estimated that the heat in the furnace produces hydrogen, which is the same as the hydrogen explosion of No. 1 and No. 3. The nuclear fuel rod itself is not on fire ." Zhiye xingnan also said that the No. 2 reactor may have suffered some damage in this mo
C ++ brush question -- 2713: function --- calculate the power of x to the power of y, set the power of yx to the power of 8x to calculate yCompile the function POW. The function declaration is as follows:Int POW (int x, int y); // evaluate the function declaration of the Power
After the power of 4 is written in binary form, it is easy to find that there is only one 1 in binary (1 in the odd position), and 1 followed by an even number of 0; therefore, the problem can be converted to determining whether an even number of zeros is followed by 1. The binary number of the integer power of 4 is (4) 100, (16) 10000, (64) 1000000 ...... In addition, the
A Power distribution System (PDS) is a subsystem that allocates power from power source to each device and device that needs power in the system. In all electrical systems there are power distribution systems, such as the lighting system for a building, an oscilloscope, a PC
The adjustment tube of the linear power supply is working in a magnified state, so the heat is generated and the efficiency is low (about 35%). A large heat sink is required, and a large power frequency transformer is also required, the transformer will be larger when multiple voltage outputs are to be made.The adjustment tube of the switch power supply is workin
