. When the control switch K in Figure 1-11-A is suddenly switched from the on state to the off state, the energy storage inductance L will release its stored energy (magnetic energy) through the back-to-force, the back-EMR generated by the energy storage inductance L is:
Negative signs in the formula indicate that the polarity of El is opposite to that of El in the (1-35) formula, that is, the polarity of the Back-

Crontab avoids repeated tests that have not been executed within the cycle. crontab instance
If a script is running for 30 minutes, you can set the script interval to at least one hour in Crontab to avoid conflicts. The worst case is that the script is not completed within the execution cycle, and the second script starts to run again. How can we ensure that only one script instance is running? A good method is to use lockf (lockf in FreeBSD 8.1 and flock in CentOS 5.5) to check whether a file l

Impala and Spark SQL beat other people on small data volumes of queries ;
Impala and Spark SQL defeated others on a complex join of large data volumes ;
Impala and Presto perform better on concurrent testing .
Compared to benchmark tests 6 months ago, all engines have a 2-4-fold performance boost.

energy storage inductance L. During this period, the voltage El at both ends of the energy storage inductance L is:El = LDI/dt = UI -- k connection period (1-19)Perform the following points on the (1-19) formula:
In the formula, Il is the instantaneous value of the L current flowing through the energy storage inductor, t is the time variable, and the initial current of I (0), that is, before the control switch K is switched on instantly, the current flowing through the energy storage inductor
UI first supplies power to the N1 winding of the primary coil of the transformer t, and the current at both ends of the N1 winding of the primary coil of the transformer will generate the self-inductive potential E1. At the same time, through the action of mutual m, the induction EMF E2 will also be generated at both ends of the N2 winding of the transformer secondary coil. When the control switch K is suddenly switched from the on-off state to the off state, the energy (magnetic energy) stored

Background
In virtualized cloud environments, Hadoop can have better "resiliency", which is an important advantage of cloud computing, such as Amazon's EMR (elasticmapreduce) service, where users can quickly deploy a Hadoop cluster in the cloud to run computing tasks, And users can dynamically add or remove compute nodes to the cluster.
There is a potential problem, HAODOP data nodes are not inherently "resilient", and deleting a data node means rep
