Fix hadoop short circuit reading can not enabled in some environments.
- Revert #21430 because it will cause performance degradation issue.
- Add `$HADOOP_CONF_DIR` to `$CLASSPATH`.
- Remove empty `hdfs-site.xml`. Because in some environments it will cause hadoop short circuit reading can not enabled.
- Copy the hadoop common native libs(which is copied from https://github.com/apache/doris-thirdparty/pull/98
) and add it to `LD_LIBRARY_PATH`. Because in some environments `LD_LIBRARY_PATH` doesn't contain hadoop common native libs, which will cause hadoop short circuit reading can not enabled.
As we know, log4j2 some times may be bottleneck in doris fe when there are many logs to be output in sync mode while asynchronous logging has a better performance， and we find that capturing caller location has a similar impact across all logging libraries, and slows down asynchronous logging by about 30-100x. so, here we provide three log mode for log4j2 to meet the needs of different users.

1. cast string literal to date like type should not be an implict cast
2. the string representation of float like type should not be scientific notation
3. the data type of like function's regex expr should be string type even if it's a null literal
4. add -Xss4m in fe.conf to prevent stack overflow in some case
1. Introduce hadoop libhdfs
2. For Linux-X86 platform, use the hadoop libhdfs
3. For other platform, use libhdfs3, because currently we don't have hadoop libhdfs binary for other platform

4. LDAP configuration supports the `admin show config` and `admin set config` commands.
1 Avoid sending tasks if there is no data to be consumed
By fetching latest offset of partition before sending tasks.(Fix [Optimize] Avoid too many abort task in routine load job #6803 )
2 Add a preCheckNeedSchedule phase in update() of routine load.
To avoid taking write lock of job for long time when getting all kafka partitions from kafka server.
3 Upgrade librdkafka's version to 1.7.0 to fix a bug of "Local: Unknown partition"
See offsetsForTimes fails with 'Local: Unknown partition' edenhill/librdkafka#3295
4 Avoid unnecessary storage migration task if there is no that storage medium on BE.
Fix [Bug] Too many unnecessary storage migration tasks #6804
This reverts part of commit 11ec38dd6fd9f86632d83c47bd9d8bc05db69a2b(#6736)
Because it will cause view query problem described in #6792
The following bug fix kept:
1. Fix the problem that the WITH statement cannot be printed when UNION is included in SQL
1. Change word of palo to doris in conf file.
2. Set default meta_dir to ${DORIS_HOME}/doris-meta
3. Comment out FE meta_dir, leave it to ${DORIS_HOME}/doris-meta, as exsting in FE Config.java.
4. Comment out BE storage_root_path, leave it to ${DORIS_HOME}/storage, as exsting in BE config.h.
NOTICE: default config is changed.
All FE logs are now with suffix yyyyMMdd or yyyyMMddHH, specified by 2 new
configurations: 'sys_log_roll_interval' and 'audit_log_roll_interval'
All FE logs roll at max size of 1024MB(default), specified by new
configuration: 'log_roll_size_mb'
By default, the new FE logs will look like this:
log/
fe.audit.log
fe.audit.log.20190524-1
fe.audit.log.20190523-2
fe.log
fe.log.20190524-1
fe.log.20190524-2
fe.log.20190523-3
fe.warn.log
fe.warn.log.20190524-1
fe.warn.log.20190523-2
fe.gc.log.20190524
Configurations 'sys_log_roll_mode' and 'audit_log_roll_mode' are deprecated.
