>
> Key: FLINK-21062
> URL: https://issues.apache.org/jira/browse/FLINK-21062
> Project: Flink
> Issue Type: Bug
> Components: Connectors / ElasticSearch, Table SQL / Ecosystem
> Affects Versions: 1.12.0
> Reporter: xiaozilong
> Priority: Major
>
> The program will throws NPE when using the dynamic Index in elasticsearch connector.
> The DDL like:
> {code:java}
> create table bigoflow_logs_output(
> jobName VARCHAR,
> userName VARCHAR,
> proctime TIMESTAMP
> ) with (
> 'connector' = 'elasticsearch-7',
> 'hosts' = 'http://127.0.0.1:9400',
> 'index' = 'flink2es-{proctime|yyyy-MM-dd}'
> );
> {code}
> The problem mayby that the method `AbstractTimeIndexGenerator#open()` is not called when `AbstractTimeIndexGenerator` is initialized.
> The exception stack is as follows:
> {code:java}
> java.lang.NullPointerException: formatter
> at java.util.Objects.requireNonNull(Objects.java:228) ~[?:1.8.0_60]
> at java.time.LocalDateTime.format(LocalDateTime.java:1751) ~[?:1.8.0_60]
