   ### Search before asking
   
   - [X] I searched the [issues](https://github.com/apache/linkis/issues) and found no similar issues.
   
   
   ### Linkis Component
   
   linkis-computation-governance
   
   ### Steps to reproduce
   
   1. When there are many deployed ECMs and the concurrency is high, an exception may be thrown: Comparison method violates its general contract!
   2. The comparison method provided by the code is: when memory, CPU, and the number of instances are all large, return -1; when memory, CPU, and the number of instances are all equal, return 0; in all other cases, return 1.
   3. There may be situations where, when the memory of A is larger than that of B, and the CPU of B is larger than that of A, the comparison between A and B will always return 1.
   
   ### Expected behavior
   
   Modify the rules of the comparator to prevent violating the general contract of the comparator.
   
   ### Your environment
   
   - Linkis version used: 1.4.0
   - Environment name and version:
       - jdk 1.8.0_144
