The io related codes may be used by new modules, so It's better to move them to fe-common.
The modification to fe-core is frequent, but there are many generated java files by thrift
will slow down the compilation, so It's better to move thrift generation process to fe-common.
Currently both log4j1 and log4j2 are used, which leads to logs are written to wrong files.
Our modification will remove log4j1 from dependency, use slf4j + slf4j -> log4j2 instead.
This CL mainly changes:
1. Add 2 new FE modules
1. fe-common
save all common classes for other modules, currently only `jmockit`
2. spark-dpp
The Spark DPP application for Spark Load. And I removed all dpp related classes to this module, including unit tests.
2. Change the `build.sh`
Add a new param `--spark-dpp` to compile the `spark-dpp` alone. And `--fe` will compile all FE modules.
the output of `spark-dpp` module is `spark-dpp-1.0.0-jar-with-dependencies.jar`, and it will be installed to `output/fe/spark-dpp/`.
3. Modify some bugs of spark load
Fix#3403
The new version of Guava has move the `toStringHelper` from `Object` to `MoreObject`.
This CL has passed our test environment, and looks running well.
The index name in MaterializedViewMeta is still with `__doris_shadow` prefix
after schema change finished.
In this CL, I just remove the index name field in MaterializedViewMeta,
so that it would makes managing change of names less error-prone.
This CL implements a simulated FE process and a simulated BE service.
You can view their specific usage methods at
`fe/src/test/java/org/apache/doris/utframe/DemoTest.java`
At the same time, I modified the configuration of the maven-surefire-plugin plugin,
so that each unit test runs in a separate JVM, which can avoid conflicts caused by
various singleton classes in FE.
Starting a separate jvm for each unit test will bring about 30% extra time overhead.
However, you can control the number of concurrency of unit tests by setting the `forkCount`
configuration of the maven-surefire-plugin plugin in `fe/pom.xml`. The default configuration
is still 1 for easy viewing of the output log. If set to 3, the entire FE unit test run time is about
4 minutes.
From January 15th, 2020, Requests to http://repo1.maven.org/maven2/ return a 501 HTTPS Required status.
So switch central repository url from http to https
[Tag System]
This CL includes 2 parts:
Add classes related to "tag"
Resource: is the collective name of the nodes that provide various service capabilities in Doris cluster.
Tag: A Tag consists of type and name.
TagSet: TagSet represents a set of tags.
TagManager: maintains 2 indexes:
one is from tag to resource.
one is from resource to tags
ISSUE #1723
Using JSON as serialization methods of metadata
Introduce GSON library to serialize the new classes mentioned above.
ISSUE #2415#2389
GSON's version is updated to 2.8.6
1. upgrade log4j to 2.12.1
2. Add 2 new FE config:
'sys_log_delete_age' and default is '7d', for sys log.
'audit_log_delete_age' and default is '30d', for audit log.
it means if a log's last modification time is 7/30 days ago, it will be deleted.
