Hadoop EqualizerWhile Hadoop is running, its datanode blocks become increasingly unbalanced, and unbalanced clusters can cause some datanode to be relatively busy.The Hadoop equalizer is a daemon. It re-allocates blocks, moving blocks from busy datanode to relatively idle datanode. At the same time, adhere to the replica policy, the replicas scattered to different racks, to reduce the data corruption rate.Cluster equalization Criteria: the utilization

capabilities of the server.7. SED shortest expected delay . In fact, SED is similar to WLC, except that the number of inactive connections is not considered. The algorithm is: (the number of active connections +1) *256÷ weight, the same calculated value of the small server priority is selected.8. NQ never queue . Improved SED algorithm. We think about the situation in order to "never queue", that is, the number of connections to the server is 0, then if there is a server connection number of 0,

÷ weight, the same computed value of a small server priority is selected. 8, NQ never line up. An improved SED algorithm. We think about what circumstances can "never queue", that is, the number of connections to the server is 0, then if there is a server connection number of 0, the equalizer directly forwarded the request to it, without having to go through the SED calculation. 9, LBLC based on the least local connection. The

priority is selected. Benefits: You can allocate requests based on the capabilities of the server. Sed the shortest expected delay. In fact, SED is similar to WLC, except that the number of inactive connections is not considered.

Sharding:-------------------------------------------------Sharding:------Sh.status () can see the status of the cluster: Shard summary information, database summary information, collection summary information.The primary shard differs from the primary node in the replica set. The primary shard refers to the entire replica set that makes up the Shard, whereas the primary node in the replica set refers to a single server that can handle write req

Order \ (G_{tx} (t) \), \ (G_{rx} (t) \), \ (H^{-1} (t) \) respectively represent the impulse response of the transmit filter, the impulse response of the receiving filter, and the impulse response of the equalizer.

Equalization Device Cool music to meet the needs of different song quality, added equalizer related settings: A) Entrance: In the Music Box interface at the bottom of the Set button, you can see the "EQ" (Equalizer) button, click on this button to call the Equalizer Settings panel (pictured below) B) Equalizer
