1. Disable the MySQL client and LZO library by default when building the Doris.
MySQL client library is used for MySQL external table feature.
This feature will be replaced by the new ODBC external table soon.
LZO library is used to compress/decompress data of some old data format of Doris,
which is no longer used anymore.
2. Add missing license to some files.
3. For all non-Apache-License code, all are explained in NOTICE file and the corresponding license is declared.
4. Remove the js source code from webroot, it will be downloaded as thirdparty
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
This CL mainly changes:
1. Reorganized the code logic to limit the supported json format to two, and the import behavior is more consistent.
2. Modified the statistical behavior of the number of error rows when loading in json format, so that the error rows can be counted correctly.
3. See `load-json-format.md` to get details of loading json format.
Format of some docs are incorrect for building the doc website.
* fix a bug that `gensrc` dir can not be built with -j.
* fix ut bug of CreateFunctionTest
`cmake` has been checked by `check_prerequest`, not needed to check it
twice, and now `CMAKE_CMD` is a command not a file, check it by '-f'
in shell will report an error.
**Authorization checking logic**
There are some problems with the current password and permission checking logic. For example:
First, we create a user by:
`create user cmy@"%" identified by "12345";`
And then 'cmy' can login with password '12345' from any hosts.
Second, we create another user by:
`create user cmy@"192.168.%" identified by "abcde";`
Because "192.168.%" has a higher priority in the permission table than "%". So when "cmy" try
to login in by password "12345" from host "192.168.1.1", it should match the second permission
entry, and will be rejected because of invalid password.
But in current implementation, Doris will continue to check password on first entry, than let it pass. So we should change it.
**Permission checking logic**
After a user login, it should has a unique identity which is got from permission table. For example,
when "cmy" from host "192.168.1.1" login, it's identity should be `cmy@"192.168.%"`. And Doris
should use this identity to check other permission, not by using the user's real identity, which is
`cmy@"192.168.1.1"`.
**Black list**
Functionally speaking, Doris only support adding WHITE LIST, which is to allow user to login from
those hosts in the white list. But is some cases, we do need a BLACK LIST function.
Fortunately, by changing the logic described above, we can simulate the effect of the BLACK LIST.
For example, First we add a user by:
`create user cmy@'%' identified by '12345';`
And now user 'cmy' can login from any hosts. and if we don't want 'cmy' to login from host A, we
can add a new user by:
`create user cmy@'A' identified by 'other_passwd';`
Because "A" has a higher priority in the permission table than "%". If 'cmy' try to login from A using password '12345', it will be rejected.
1. Add Config.max_routine_load_concurrent_task_num instead of the old one
2. Fix a bug that SHOW ALTER TABLE COLUMN may throw Nullpointer exception
3. Fix some misspelling of docs
* Add param of specified thirdparty path
1. The thirdparth path can be specify on build.sh: ./build.sh --thirdparty /specified/path/to/thirdparty
2. If there are only thirdparty param of build.sh, it will build both fe and be
3. Add unit test of routine load stmt
4. Remove source code in docker image
* Add DORIS_THIRDPARTY env in docker image
1. Set DORIS_THIRDPARTY env in docker image. The build.sh will use /var/local/thirdparty instead of /source/code/thirdparty
2. remove --thirdparty param of build.sh
* Change image workdir to /root
1. No one can set root password expect for root user itself
2. NODE_PRIV cannot be granted.
3. ADMIN_PRIV and GRANT_PRIV can only be granted or revoked on *.*
4. No one can modifly privs of default role 'operator' and 'admin'.
5. No user can be granted to role 'operator'.
Fixed: the running load limit should not be applied to replay logic. It will cause replay or loading image fail.
Changed: optimize the problem of too many directories under mini load directory.
Fixed: missing password and auth check when handling mini load request in Frontend.
Fixed: DomainResolver should start after Frontends transfer to a certain ROLE, not in Catalog construction methods.
Fixed: a stupid bug that no one can set password for root user... fix it: only root user can set password for root.
Fixed: read null data twice
When reading data with a null value, in some cases, the same data will be read twice by the storage engine,
resulting in a wrong result.The reason for this problem is that when splitting,
and the start key is the minimum value, the data with null is read.
Fixed: add a flag to prevent DomainResovler thread start twice.
Fixed: fixed a mem leak of using ByteBuf when parsing auth info of http request.
Fixed: add a new config 'disable_hadoop_load', default is false, set to true to disable hadoop load.
Changed: add detail error msg of submitting hadoop load job in show load result.
Fixed: Backend process should be crashed if failed to saving header.
Added: exposure backend info to user when encounter error on Backend. for debugging it more convenient.
Fixed: Should remove fd from map when inputstream or outputstream is closed in Broker process.
Fixed: Change all files' LF to unix format.
