…Support Kerberos Ticket Auto-Renewal (#44916) ### Background The current implementation uses the HadoopUGI method, which invokes the ugiDoAs function for each operation to log in and execute actions based on the configuration. However, this approach has the following issues: - Lack of Auto-Renewal: If the Kerberos TGT (Ticket Granting Ticket) expires, manual re-login is required as there is no support for automatic ticket renewal. - Redundant Login Overhead: Each operation requires reinitializing or checking UserGroupInformation, potentially causing performance bottlenecks. - Complex Management: The HadoopUGI design does not unify the lifecycle management of UGI instances, leading to duplicated logic across the codebase. ### Objective - Auto-Renewal: Automatically renew Kerberos credentials when the TGT is expired or near expiry. - UGI Caching: Maintain reusable UserGroupInformation instances during their lifecycle to avoid repetitive logins. - Unified Management: Simplify the management of UGI instances and Kerberos credentials.
