When fe replay rollup job(v1) with deleted table, it will throw null pointer exception and exit.
This commit ignore this error and print a warning log to avoid fe exit.
Fixed#4571
Change-Id: I302b554a94d42aee645db6b224cd989e00cd3ca6
Many tables are so large that need seperate partitions with "HOUR" time unit.
But now dynamic partition doesn't support "HOUR" time unit and it was marked as "TODO".
So I support the feature and it works.
Add tracing broker log. When fe get filestatus for distributing load task to broker,
the broker maybe get empty files and not give correct error code.
Add this log to easy track which broker process filestatus operation and we can get the error log.
We store all table ids involved in the Load Job in TransactionState.
However, for Hadoop Load job, table ids are set incorrectly.
This caused the WAITING_TXN phase to not correctly wait for the completion
of the previous load transaction when doing the alter table,
which caused some data version loss problems.
we can create odbc_table use SQL like
```
CREATE EXTERNAL TABLE `baseall_oracle` (
`k1` decimal(9, 3) NOT NULL COMMENT "",
`k2` char(10) NOT NULL COMMENT "",
`k3` datetime NOT NULL COMMENT "",
`k5` varchar(20) NOT NULL COMMENT "",
`k6` double NOT NULL COMMENT ""
) ENGINE=ODBC
PROPERTIES (
"host" = "192.168.0.1",
"port" = "8086",
"user" = "happenlee",
"password" = "doris",
"database" = "doris",
"table" = "baseall",
"driver" = "Oracle 19 ODBC driver",
"type" = "oracle"
);
```
Now we only support Oracle and MySQL Database and this feature default turned off by conf enable_odbc_table.
Main CL:
1. Copy the code from BE to implement the `str_to_date()` function in FE.
2. `str_to_date("2020-08-08", "%Y-%m-%d %H:%i:%s")` will return `2020-08-08 00:00:00` instead of `2020-08-08`.
It is possible to report "Illegal column/field reference'table2.DORIS_DELETE_SIGN' of semi-/anti-join"
when executing a semi/anti join statement on a table with hidden columns.
This is because the filter conditions of semi/anti join cannot added in the where statement.
Now we add delete flag related where predicate in OlapScanNode level.
1. Analyze what mode of cache can be used by query
2. Query cache before executing query in StmtExecutor
3. Two cache mode, sqlcache and partitioncache, are implemented
The param of rand() function should be literal, but current compiler ignore to
validate the literal param of rand function, it is validated in execution step.
This PR make it validated in compile step, and make it more earlier to find the usage error of rand() function.
In DistributedPlanner, do not add the unnecessary Exchanges.
For case 1, we only need to judge that the table's distribute hash keys is a subset of the aggregate keys.
For case 2, we should judge two conditions:
- partition keys are also hash keys.
- the table's distribute hash keys is a subset of the aggregate keys.
1. fix write dpp result when dpp throw exception
2. boolean value：true, false(IgnoreCase), 0, 1
3. wrong dest column for source data check
4. support * in source file path
5. if job state is cancelled or finished, submitPushTasks would throw all partitions have no load data exception,
because tableToLoadPartitions was already cleaned up
#3433
In the process of historical data transformation of materialized views, it may occur that the transformation fails due to data quality.
Add an error status code ：OLAP_ERR_DATE_QUALITY_ERR to determine if a data problem is causing the failure
#3344
Send fields after first row arrived so that error packet can be send to client
when exception thrown from coord.getNext().
Golang and Python can not identify error if fields packet arrived before error packet.
This cl will use yarn command as follows to kill or get status of application running on YARN.
```
yarn --config confdir application <-kill | -status> <Application ID>
```
1. Support convert(expr, target_type) function, which is same as CastExpr
2. Support cast (expr as signed/unsigned int)
This is just for compatibility, the signed/unsigned specification is meaningless.
The mv column with bitmap_union function is named `mv_bitmap_union_k1` inside of Doris.
But this column name should not be shown to user in `Show Proc` stmt.
Instead, using define expr is easier to understand.

The DECIMAL, CHAR, VARCHAR have their own scale and precision in column.
The mv column should keep those scale and precision.

1. The base column of bitmap_union could must be integer. The largeint is not supported too.
2. The base column of hll_union could not be decimal.
Check error msg of const expr in Union Node
If user wants to insert a negative number into bitmap mv, Doris will thrown exception 'invalid input'.
The const value in Union Node is checked in this commit.
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
Since the Segment V2 has been released for a long time, we should make it as default storage format for newly created table.
This CL mainly changes:
1. For all newly created tables, their default storage format is Segment V2.
2. For all already exist tablets, their storage format remain unchanged.
3. Fix bugs described in Fix#4384 and Fix#4385
We have changed most of our serialization methods to json. In order to be compatible with previous data, these classes still retain the readFields method. Some prs that involve modifying metadata often modify the readFields method. To avoid this, we should Mark these methods as Deprecated #4398
