In this case, forward to master will throw catalog or db not found exception:
Connect to a follower:
1. create database test
2. use test
3. drop database test
4. create database test
This is because after step 2, the default db in follower has been set to `test`, drop database will not change the default db. In step 4, the default db `test` is set and forwarded to master, and master will fail to find it because it is already dropped.
This pr is to set the default catalog and db only when they exist.
The actual reason is that, when Follower handle the `drop db` stmt, it will forward to master to execute it, but can not
unset its own "current db"
Fix three bugs:
1. Hudi slice maybe has log files only, so `new Path(filePath)` will throw errors.
2. Hive column names are lowercase only, so match column names in ignore-case-mode.
3. Compatible with [Spark Datasource Configs](https://hudi.apache.org/docs/configurations/#Read-Options), so users can add `hoodie.datasource.merge.type=skip_merge` in catalog properties to skip merge logs files.
When a disk io error occurs, errors may occur when reading and writing files in the inverted index. This PR adds error checking to prevent empty files from being generated.

extends #23784
Problem:
When inferring predicate，we lost cast of source expressions and some datatype derivation.
Example:
a = b and cast(a as targetType) = constant
(cast(a as targetType) = constant ) this expression is define as source expression.
we expect getting cast(b as targetType) = constant instead of b = constant
Reason:
When inferring predicate, we will compare original type of a and b. if they can be cast
without precision lost, a new predicate would be created. But created predicate forgot
to cast to target type
Solved:
Add cast to target type, and open make other datatype valid also.
* [improvement](shutdown) not print thread pool error stack trace when shutdown
when thread pool shutdown, should not print error stack trace, it is very confuse.
arrow flight server should not call shutdown, if it is not enabled, because it will print error stack.
remove service unavailable from thrift because it is useless.
Part of this PR need to pick to 2.0 branch.

before the lambda function Expr not implement toSqlImpl() function.
so it's call parent function, which is not suit for lambda function.
and will be have error when create view.
