             Summary: Meeting NPE when using the dynamic Index in elasticsearch connector
                 Key: FLINK-21062
                 URL: https://issues.apache.org/jira/browse/FLINK-21062
             Project: Flink
          Issue Type: Bug
          Components: Connectors / ElasticSearch
    Affects Versions: 1.12.0
            Reporter: xiaozilong


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' = '<a href="http://127.0.0.1:9400'">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.
