> LazySimpleSerDe.LazyMap doesn't handle the condition of when map key is
> another column value.
> eg:
> CREATE TABLE `demo`(
>
> `create_timestamp` bigint,
> `ctime` string,
> `event_data` map<string,string>
> )
> ROW FORMAT SERDE
> 'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
> STORED AS INPUTFORMAT
> 'org.apache.hadoop.mapred.TextInputFormat'
> OUTPUTFORMAT
> 'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
> add data
> INSERT INTO TABLE demo
> select
> 1511192567909,
> '1511192567909',
> map('1511192567909', '05020918127a82816437ba9edac17fca42601');
> Do query:
> SELECT
> create_timestamp,
> ctime,
> event_data,
> event_data[create_timestamp],
> event_data[ctime]
> FROM demo;
> RES：
> | create_timestamp | ctime | event_data

> // Got a match, return the value

> {code}
> When the key is a cloumn and don't need convert, the key will be a
> LazyPrimitive object.
> keyI = lazyKeyI.getWritableObject() is actual primitive writable objects.
> keyI.equals(key) will be false.
