Use same UUID as query ID and load ID of a load execution plan.
Each load execution plan has a load ID, and as a plan, there is also a query ID.
We can use same UUID as query ID and load ID, for tracing the load process more easily.
Change the load ID when retrying a load execution plan.
When a load execution plan retry, the load ID should be changed, otherwise BE can not
distinguish the old and new load requests.
Cancel the running loading task when cancelling the broker load.
When user cancel a broker load, the running loading task should also be cancelled, or
it may occupies the worker thread for a long time.
Remove the unnecessary query report when doing load execution plan.
Only the last query report is needed.
Add a new BE config tablet_writer_rpc_timeout_sec.
It is used for RPC of tablet sink. The default is 600 seconds. which is long enough for flushing
about 6GB data. The long timeout config will reduce the possibility of encountering fail to send batch error when loading.
Use streaming_load_max_mb instead of mini_load_max_mb in BE config.
Add more logs for tracing a broker load process easily.
Mini load is now using stream load framework. But we should keep the
mini load return behavior and result json format be same as old.
So PUBLISH_TIMEOUT error should be treated as OK in mini load.
Also add 2 counters for OlapTableSink profile:
SerializeBatchTime: time of serializing all row batch.
WaitInFlightPacketTime: time of waiting last send packet
Mini load timeout needs to be added in plan options.
The timeout property has been added in request of process put.
Otherwise, the timeout of mini load is useless.
Add log of label, txn and query id in mini load
* This commit has brought contribution to streaming mini load
The operation of streaming mini load is sames as previous. Also, user can check the load by frontend.
The difference is that streaming mini load finish the task before reply of REST API while the non-streaming only register a load.
* When updating doris
Updating fe or be firstly are also supported. After fe and be are updated, the streaming mini load will take effect.
* For multi mini load
The non-streaming mini load still has been used by multi mini load. The behavior of multi mini load has not been changed.
* Add a interface named isSupportedFunction
This function is used to protect the correctness of new feature which consists of be and fe during updaing.
1. Unify the thrift rpc timeout from BE to FE.
Add a BE config 'thrift_rpc_timeout_ms', default is 5000
2. Add hostname in "show proc '/frontends';" stmt result.
3. Fix a lock order bug in Load.java
* Reduce UT binary size
Almost every module depend on ExecEnv, and ExecEnv contains all
singleton, which make UT binary contains all object files.
This patch seperate ExecEnv's initial and destory to anthor file to
avoid other file's dependence. And status.cc include debug_util.h which
depend tuple.h tuple_row.h, and I move get_stack_trace() to
stack_util.cpp to reduce status.cc's dependence.
I add USE_RTTI=1 to build rocksdb to avoid linking librocksdb.a
Issue: #292
* Update
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.

4. A lot of bugs fixed.
5. Performance improvement.
1. Implement Backend http server using libevent instead of mongoose.
2. Remove Old Hypertable rpc framework, use brpc instead.
3. Change rpc from FE to BE to brpc.

merge to 2d4cc9e1358c980b4f726e17d036639bc31127aa (#188)
contains:
first_value with PRECEDING LEFT and NON-PRECEDING RIGHT rewrite error and count* materialize SlotDescriptor
error when referring to the slot of the current query and subquery Simultaneously.
fix join and count(*) materialize SlotDescriptor error.
fix materialize scannode's conjuncts bug.
remove no used materialization work.
it have to evaluate orderby in subquery because we limit the number of rows returned by subquery.
the method of judging limit is wrong.
user info is missing when retrying to call load check.
It's wrong to pass aggregate function when it's param is not materialized.
InsertStmt does not pass the session param to observer.
