Engine Description

Starting from Hengshi-sense:4.3, an embedded Doris engine is provided. If you have specific requirements for the engine type, please confirm the engine type with the staff before obtaining the installation upgrade package.

Doris Engine Configuration

Engine configuration needs to be set before startup in the conf/hengshi-sense-env.sh file under the installation root directory. The export keyword must be added before the variables. The relevant field descriptions are as follows:

Field	Required	Type	Description
DORIS_FE_HOSTS	No	ARRAY	Doris engine Fe (Frontend) deployment machine information. This option is mandatory when the deployment environment has virtual network cards or the machine has multiple network cards. (10.10.10.x) (10.10.10.x 10.10.12.x)
DORIS_BE_HOSTS	No	ARRAY	Doris engine Be (Backend) deployment machine information. This option is mandatory when the deployment environment has virtual network cards or the machine has multiple network cards. (10.10.10.x) (10.10.10.x 10.10.12.x)
DORIS_FE_QUERY_PORT	No	INTEGER	Doris FE query connection port via MySQL protocol. Default value: 9030
DORIS_BE_BE_PORT	No	INTEGER	Port number of the Thrift server on BE, used to receive requests from FE. Default value: 9060
HS_DORIS_ENGINE_DATASET_DATAB	No	STRING	Business database name used internally by HENGSHI SENSE, storing dataset-related information.
HS_DORIS_ENGINE_TMP_DATABASE	No	STRING	Business database name used internally by HENGSHI SENSE, storing temporary tables and data integration file information.
HS_DORIS_ENGINE_OUTPUT_DATABASE	No	STRING	Business database name used internally by HENGSHI SENSE, storing public data information.
HS_DORIS_ENGINE_USER	No	STRING	Internal Doris user name provided by HENGSHI SENSE.
HS_DORIS_ENGINE_PWD	No	STRING	Internal Doris user password provided by HENGSHI SENSE.

Notes

1. In a VM standalone deployment environment, if there are multiple network interfaces or virtual network interfaces in the environment, the conf/hengshi-sense-env.sh configuration file must configure the DORIS_FE_HOSTS and DORIS_BE_HOSTS parameters to avoid startup failures due to network factors.

ip addr | sed -rn '/docker/{N;N;/inet/d}; s/127.0.0.1//; s/.*inet (addr:)?(([0-9]*\.){3}[0-9]*).*/\2/p'
# Multiple IPs are output as a result, indicating the presence of multiple network interfaces or virtual network interfaces in the environment

2. In a VM cluster deployment environment, it is recommended to replace the Hostname with IP address information in the hosts file for doris-related configuration items to avoid startup failures due to network factors.

#Note that the number of doris-fe needs to be configured as an odd number
[doris-fe] # It is recommended to use IP information for configuration, hostname configuration may cause startup failure
Node-A master=true
Node-B
Node-C

[doris-be] # It is recommended to use IP information for configuration, hostname configuration may cause startup failure
Node-A
Node-B
