----------------------------------
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' = '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:
java.lang.NullPointerException: formatter at
java.util.Objects.requireNonNull(Objects.java:228) ~[?:1.8.0_60] at
