各位好，

今天在测试Flink SQL 无法启动，错误日志如下。请问下配置yaml文件的格式需要注意下什么,分割符号能否支持特殊的符号如 hive建表语句中的分隔符'\036'，详细报错日志如下。

Execution properties allow for changing the behavior of a table program.

execution: type: streaming # required: execution mode either 'batch' or 'streaming' result-mode: table # required: either 'table' or 'changelog' max-table-result-rows: 1000000 # optional: maximum number of maintained rows in

'table' mode (1000000 by default, smaller 1 means unlimited)

time-characteristic: event-time # optional: 'processing-time' or 'event-time' (default) parallelism: 1 # optional: Flink's parallelism (1 by default) periodic-watermarks-interval: 200 # optional: interval for periodic watermarks(200 ms by default) max-parallelism: 16 # optional: Flink's maximum parallelism (128by default) min-idle-state-retention: 0 # optional: table program's minimum idle state time max-idle-state-retention: 0 # optional: table program's maximum idle state time restart-strategy: # optional: restart strategy type: fallback # "fallback" to global restart strategy by default

Deployment properties allow for describing the cluster to which table programsare submitted to.
