point1. Cannot be modified after creation: Spark emphasizes immutability, and in most scenarios tends to create new objects instead of modifying old objects. 2. By viewing data manipulation records, you can efficiently recalculate lost data. 3. Support for the operation of distributed data. Both 4.DataFrame and RDD can be created from the following data sources: (1) A Python dataset for distributed storage. (2) Dataframe or other spark datasets in pandas. (3) files in HDFs or other file syste

A. About stacking technology: How does the 1.Catalyst 3500XL/2900XL stack be implemented? A. Special tiered cabling is required, 1 m long or 50 cm long (cab-gs-1m or cab-gs-50cm) and a dedicated gigabit stacked card Gigastack GBIC (WS-X3500-XL) (which already contains cab-gs-50cm stacked cables). B. There are 2 stacking methods available: Daisy Chain (providing 1G of bandwidth) or point-to-point method (2G bandwidth available). C. 2 ways to do back

Today gigabit as the backbone, hundred trillion for access to the mainstream structure, will gradually to the million trillion backbone, gigabit access to the structure of the transition.

must be configured simultaneously under the port. If this command is not run, the final effect of this mode is the same as that of the source IP address filtering mode. Apply IP source protection to the trunk interface that is in the 3560 downlink. This interface is a non-trusted interface. Because 2960 does not provide IP source protection, IP spoofing attacks may occur on data packets from 2960. The Application of IP source protection on the trunk

I have two sets of 3560 to do HSRP, the following connected more than 10 2950 or 2960 (each with two lines, one will be blocked by the spanning Tree Protocol), 3560 is zoned 3 VLAN1, 2, 3, the following 29 is not zoned VLAN, The interface between the two ends of the switch is set to access mode, and now the problem is that 29 of the 3560vlan1 are not reported, and 29 of VLAN2 and 3 are reporting similar%cdp

a modification to smooth over. 2. Allow the user to use matching all (Match-all) and match any (match-any) in the same classmap. For example, 4 matching criteria: A, B, C, and D. Now you want Classmap to match a, or match B, or both C and D, you can use Classmap nesting: Create a new classmap, defined to match all (Match-all) new criteria for matching E to match both C and D; then define another match for any (Match-any) Classmap, to match a, or B, or E (that is, match both C and D).

original network equipment, the connection between the ATM and Gigabit Ethernet networking technologies is involved, this article introduces the solution to this problem based on our practical experience. During the Phase I project construction of our campus network, the backbone uses the ATM technology and installs a certain number of network devices. The backbone switch uses the 3COM Corebilder 7000HD, which currently works normally. In the phase II project construction, the backbone adopts t
