------------------------------------
Summary: Multi-tenant history server
Key: SPARK-45126
URL: https://issues.apache.org/jira/browse/SPARK-45126
Project: Spark
Issue Type: Wish
Components: Spark Core
Affects Versions: 3.4.1
Reporter: Ramu Ramaiah
Spark history server makes use of the configuration
"spark.history.fs.logDirectory" to locate the log events. This works well for a
single tenant. When it is used for a multi-tenant deployment, the log events of
multiple tenants are stored in a single directory which does not provide a
logical separation of events for each tenant.
The proposal/wish is to have a support for Multi-tenant history server,
where-in the configuration "spark.history.fs.logDirectory" can be a base
directory. The sub-directories can contain the log events for each tenant. The
sub-directories can be named after each tenant, for e.g. "tenant1", "tenant2"
etc.
When it is combined to work with Spark Driver/Executor which makes use of the
property "spark.eventLog.dir", the value of this property can be appropriately
set for each tenant.
