Jark Wu commented on FLINK-19419: --------------------------------- [~caozhen1937], we HAVE TO use an specific string literal to represent {{null}}, this is controlled by {{null-string-literal}}. If users define "null-string-literal=null", that means users are aware of it, then we have to return {{null}} instead of {{"null"}} string when reading a "null" string. If users want to keep the "null" string, he/she can change the config of {{null-string-literal=null}}. > "null-string-literal" does not work in HBaseSource decoder > ------------------------------------------------------------ > > Key: FLINK-19419 > URL: https://issues.apache.org/jira/browse/FLINK-19419 > Project: Flink > Issue Type: Bug > Components: Connectors / HBase > Affects Versions: 1.11.0, 1.11.1, 1.11.2 > Reporter: CaoZhen > Priority: Minor > Labels: pull-request-available > Attachments: image-2020-09-25-21-11-36-418.png > > > > When using HBaseSoucre, it is found that "null-string-literal" does not work. > The current decoder processing logic is shown below. > `nullStringBytes` should be used when the `value` is null. > > !image-2020-09-25-21-11-36-418.png! -- This message was sent by Atlassian Jira (v8.3.4#803005)
