luoyuxia commented on FLINK-31659:
----------------------------------
Not extactly, it's not whenever as mentioned "this bug only happens with
filesystem tables. Other tables do not have this issue" by the reporter.
Back to this issue, the reason is we can't find the {{DialecFactory}} in
FlinkUserClassloader and then we throw the excpetion. Also, I found
we will catch the {{NoClassDefFoundError}} in
{{{}FactoryUtil#discoverFactories,{}}}the context that why we catch
{{NoClassDefFoundError}} can be found in
[https://github.com/apache/flink/pull/17897.|https://github.com/apache/flink/pull/17897]
"when users bring in a format module, implementing
{{{}BulkReaderFormatFactory{}}}/{{{}BulkWriterFormatFactory{}}}, but don't have
flink-connector-files in the classpath because they don't use it. E.g. you're
using {{flink-connector-kafka}} and you want to use {{{}flink-avro{}}}, which
brings in an implementation of {{{}BulkWriterFormatFactory{}}}. "
The reason of the exception reported in this Jira is similar, we bring Hive
connector as well as {{HiveDialectFactory}} . So, in method
{{formatFactoryExists#formatFactoryExists}} it will try to load
{{org.apache.flink.table.planner.delegation.hive.HiveDialectFactory}} by java
SPI, but can't find the class defination. So the exception throws.
To fix this issue, I would like to catch the {{NoClassDefFoundError}} just like
what we did in {{{}FactoryUtil#discoverFactories{}}}.
But it'll be just a fix to 1.17 & 1.16 for I'm intended to decouple Hive with
planner in 1.18, and after that the problem won't happen.

> Key: FLINK-31659
> URL: https://issues.apache.org/jira/browse/FLINK-31659
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Hive
> Affects Versions: 1.17.0, 1.16.1, 1.15.4
> Reporter: Caizhi Weng
> Priority: Major
>
> Steps to reproduce this bug:
> 1. Download a fresh 1.16.1 Flink distribution.
> 2. Add both {{flink-sql-connector-hive-2.3.9_2.12-1.16.0.jar}} and
> {{flink-shaded-hadoop-2-uber-2.8.3-10.0.jar}} into {{lib}} directory.
> 3. Start a standalone cluster with {{bin/start-cluster.sh}}.
> 4. Start SQL client and run the following SQL.
> {code:sql}
> create table T (
> a int,
> b string
> ) with (
> 'connector' = 'filesystem',
> 'format' = 'csv',
> 'path' = '/tmp/gao.csv'
> );

> b string
> ) with (
> 'connector' = 'print'
> );
