   @zhangjun0x01 ,  we flink 1.11.x does not support `CREATE TABLE IF NOT EXISTS` (see: [here](https://github.com/apache/flink/blob/release-1.11/flink-table/flink-sql-parser/src/main/codegen/includes/parserImpls.ftl#L723) ),  but flink 1.12.x starts to support it ( see:  [here](https://github.com/apache/flink/blob/release-1.12/flink-table/flink-sql-parser/src/main/codegen/includes/parserImpls.ftl#L802) ).  After upgraded the flink from 1.11.0 to 1.12.x,  the `CREATE TABLE IF NOT EXISTS` is still not working  because we've ignored the `ignoreIfExists` in [FlinkCatalog#createTable](https://github.com/apache/iceberg/pull/2135/files#diff-0ae3022739b9b55183c9aa972fadb7cdb9cb3956468f14559b3c57c5900f3953R383).  It's a bug in flink iceberg catalog intergration work so I'd prefer to fix this before the next release.  
   
   I've created a PR to handle this https://github.com/apache/iceberg/pull/2135.
