HENGSHI SENSE Startup FAQs

Kernel Parameter Issue Leading to Engine Startup Failure

text
[2023-05-06.03:39:33.960][hengshi@0c3eb9a1f944][hengshi-sense-bin:45][ INFO ]: starting engine
[2023-05-06.03:39:33.972][hengshi@0c3eb9a1f944][hengshi-sense-bin:811][ INFO ]: check resources needed if avaiable.
127.0.0.1 checkHostSysConfig fail! kernel.sem is not set properly, please check it manually in /etc/sysctl.conf and /etc/sysctl.d/*.conf
current sem: 250 32000 32 128, at least should be: '250 2018500 100 8074'
false

The possible causes of this error message are:

  • The init-os all operation was not executed correctly.

  • The init-os all operation was executed successfully, but the shell was not re-logged in as prompted to refresh the configuration.

    shell
    cd /opt/hengshi
    bin/hengshi-sense-bin init-os all
    # Then you need to re-login to the shell to refresh the configuration

Port Conflict Leading to Service Startup Failure

text
[2023-05-06.03:51:22.860][hengshi@0c3eb9a1f944][hengshi-sense-bin:773][ ERROR ]: metadb port 54320 is not avaiable.
 Resrouces needed are not available, Abort!

The above example indicates that port 54320 is already in use. The most common reasons are:

  1. The service using this port is already running.
  2. The port is occupied by another process. You can modify the port of the corresponding HENGSHI service and start it using an available port. The following command can be used to check which program is occupying the port:
shell
netstat -nlp | grep <PORT>

JDK Version Issue Causing HENGSHI Service Startup Failure

text
[2023-05-06.03:45:36.835][hengshi@0c3eb9a1f944][hengshi-sense-bin:1226][ ERROR ]: required: java >= 11.0.0

HENGSHI service depends on JDK 11. The solution is as follows:

  • Execute init-os all, and the program will automatically fetch JDK-11 resources from the internet.

    shell
    cd /opt/hengshi
    bin/hengshi-sense-bin init-os all
  • If the deployment environment is an intranet and cannot connect to the internet, refer to Offline Environment Dependency Preparation.

Doris Engine Startup Failure

  1. Missing Configuration
text
[2023-05-06.03:51:22.860][hengshi@0c3eb9a1f944][hengshi-sense-bin:773][ ERROR ]: please set DORIS_FE_HOSTS and DORIS_BE_HOSTS params

Refer to Doris Engine Configuration for this issue.

  1. JDK Version Dependency Not Met
text
[2023-05-06.03:45:36.835][hengshi@0c3eb9a1f944][hengshi-sense-bin:1226][ ERROR ]:Doris engine is required by JDK-1.8

The Doris engine service depends on JDK-1.8. The solution is as follows:

  • Execute init-os all, and the program will automatically fetch JDK-1.8 resources from the internet.

    shell
    cd /opt/hengshi
    bin/hengshi-sense-bin init-os all
  • If the deployment environment is offline and cannot connect to the internet, refer to Offline Environment Dependency Preparation.

The root cause of this issue is that the HENGSHI service does not support using PostgreSQL versions <10 as the metadb service.
Please refer to Database Service Upgrade.
