Distributed detection mechanism

ACK

Watcher

Checkpoint

Question 5 of 33

6. Among the following options, which one is correct about the meaning of Zookeeper reliability?

Reliability is achieved through active and standby deployment

Reliability means that the update can only succeed or fail, there is no intermediate state

Reliability means that no matter which server displays the same view to the outside world

Question 6 of 33

7. In order to improve the fault tolerance of Kafka, Kafka supports partition replication strategy. Which of the following descriptions about Leader partition and Follower partition is wrong?

It is impossible for each node of a kafka cluster to be the leader and flower of each other

If the leader fails, another follower will take over (become the new leader)

Since the leader Server bears all the request pressure, considering the overall cluster, Kafka will evenly distribute the leader to each instance to ensure the overall stable performance

Kafka needs to select a leader for the replication of the partition. The leader is responsible for the read and write operations of the partition, and the other replica nodes are only responsible for data synchronization.

Question 7 of 33

8. Flume is used to collect data, and the basic unit of data transmitted by the device is?

Split

Block

Event

Packet

Question 8 of 33

9. The SoIrCloud mode is a cluster mode. In this mode, the Solr server is strongly dependent on which of the following services?

HDFS

ZooKeeper

YARN

Question 9 of 33

10. Which of the following is a node of ElasticSearch?

EsNode

Index

EsMaster

Cluster

Question 10 of 33

11. Which statement about HIVE is wrong?

The best usage scenario of Hive is the batch processing job of large data sets

Hive can realize low-latency and fast query on large-scale data sets

Hive is built on Hadoop based on static batch processing. Hadoop usually has high latency and requires a lot of overhead when submitting and scheduling

The Hive query operation process strictly follows the Hadoop MapReduce role execution model. Hive converts the user's HiveQL statement to the MapReduce Hadoop cluster through the interpreter.

Question 11 of 33

12. When deploying Fusioninsight HD, it is recommended to deploy at least a few FlumeServer nodes in the same cluster?

Question 12 of 33

13. Which of the descriptions about ordinary tables and external tables in Hive is wrong?

Create ordinary tables by default

The essence of the external table is to associate the file path already existing on HDFS with the table

When deleting a common table, metadata and data are deleted at the same time

When deleting an external table, only delete the data of the external table without deleting the metadata

Question 13 of 33

14. Which way is wrong to load data into the Hive table?

Directly load the file in the local path into the Hive table

Load the amount of files on HDFS into the Hive table

Hive supports the method of insert into a single record, so you can insert a single record directly on the command line

Insert the result set of other tables into the Hive table

Question 14 of 33

15. Which of the following is not a feature of the MapReduce component in Hadoop?

Ease of programming

Good scalability

Real-time computing

High fault tolerance

Question 15 of 33

16. In Hive, which of the following descriptions about partitions is wrong?

There can be partitions or buckets under the partition

The data table can be partitioned according to the value of a field

Each partition is a directory

The number of partitions is fixed

Question 16 of 33

17. Which of the following functions can the Shell script of Loader achieve? (Multiple choice)

View job status

Start the job

stop working

Data source query

Question 17 of 33

18. Assume that the minimum resource guarantee for each user is set to YARN.scheduler.capacity.root.QueueA.minimum-
User-limit-percent=25, then which of the following statement is wrong?

When the fourth user submits a task, each user can get up to 25% of the resources

When the second user submits a task, each user can get up to 50% of the resources

When the third user submits the task, each user can get up to 33.33% of the resources

When the fifth user submits a task, each user can get up to 20% of the resources

Question 18 of 33

19. After using the Streaming client shell command to submit the topology in the Fusioninsight HD system, I use the Strom UI to view and find that the topology has not processed data for a long time. What may be the reason? (Multiple choice)

Supervisor is a component that receives data in topology and then performs processing

There is a logic error in the topology business, and it cannot run normally after submission

The topology is too complex or the concurrency is too large, causing the worker startup time to be too long, exceeding the waiting time of the Supervisor

The slots resources of the Supervisor are exhausted. After the topology is submitted, there are no slots to start the worker process.

Question 19 of 33

20. Which of the following commands can be used to create node data?

get /node

create /node

set/node data

ls/node

Question 20 of 33

21. Which of the following descriptions about Fusioninsight CTBase is wrong?

The read-write data interface of CTBase uniformly encapsulates the interface defined by the row, automatically merges and parses cold fields, and does not need to be merged and interpreted in the application

CTBase is a cluster table development framework based on HBase

CTBase provides a set of WebUI for metadata definition, provides a table design tool only for medical use, and reduces the difficulty of table design

The java API of CTBase provides a set of interfaces for HBase connection pool management, and internal connection sharing reduces the difficulty of client application development.

001: Li

001: Mary, 001: Lily

001: Li, 001: Mary, 00l: Lily
