Some important issues need to be resolved

[Chen Xia <ca...@gmail.com>]

Hi All:

Linkis-1.0.3-RC1(RC:Release conditions) version will be released a few days
later, but there are still some  important unresolved issues, as follows:

   - L2 Issues-1136[1] [CGS-LinkisManager] Only the engine resources are
   released, but the user tag resources are not released, resulting in
   inaccurate recorded resource data.
   - L3 Issues-1137[2] [CGS-LinkisManager] In a concurrent scenario,the
   engine's locked resources are converted to used resources.
   - L3 Issues-1138[3] [MGS-LinkisServiceGateway] The memory leak problem
   of SSO login.
   - L3 Issues-1139[4] [PES-PublicService] The timeout problem of obtaining
   database connection caused by jobhistory task concurrency.
   - L2 Issues-1140[5] [CGS-LinkisManager] In the case of large
   concurrency, ResourceManager(RM) ignores the consideration of resource
   increase and decrease when the engine is released.

Importance level: L1>L2>L3>L4

These issues are planned in the official version of linkis-1.0.3 and will
be solved iteratively in the subsequent RC version of linkis-1.0.3.

*Note: RC version* is an unstable version
