1、查询表结构
show create table data_lake_ods.dws_service_subclazz_lesson_user_learn_stat_rt_v2
CREATE TABLE spark_catalog.data_lake_ods.dws_service_subclazz_lesson_user_learn_stat_rt_v2 (
`user_number` BIGINT NOT NULL,
`subclazz_number` BIGINT NOT NULL,
`clazz_number` BIGINT,
`clazz_lesson_number` BIGINT NOT NULL,
`lesson_live_property` BIGINT,
`lesson_video_property` BIGINT,
`lesson_live_length` BIGINT,
`lesson_video_length` BIGINT,
`lesson_standard_length` BIGINT,
`lesson_length` BIGINT,
`live_learn_duration` BIGINT,
`video_learn_duration` BIGINT,
`learn_duration` BIGINT,
`is_valid_live_learn` BIGINT,
`is_valid_learn` BIGINT,
`companion_learn_duration` BIGINT,
`learn_combine_duration` BIGINT,
`companion_lesson_length` BIGINT,
`is_should_attend_user` BIGINT,
`is_live_attend_user` BIGINT,
`is_combine_valid_learn_user` BIGINT,
`is_black_user` BIGINT)
USING iceberg
LOCATION 'ofs://127/user/hive/warehouse/data_lake_ods.db/dws_service_subclazz_lesson_user_learn_stat_rt_v2'
TBLPROPERTIES(

'write.metadata.previous-versions-max' = '100',
'write.update.mode' = 'merge-on-read',
'write.upsert.enabled' = 'true')2、得到hdfs存储路径后，查询最新的metadata.json文件
hdfs dfs -ls /user/hive/warehouse/data_lake_ods.db/dws_service_subclazz_lesson_user_learn_stat_rt_v2/metadata/
得到最新的文件是：/user/hive/warehouse/data_lake_ods.db/dws_service_subclazz_lesson_user_learn_stat_rt_v2/metadata/00059-1d8e6694-f873-45a3-9697-ce2762f78c3a.metadata.json
3、查看文件内容
hdfs dfs -cat /user/hive/warehouse/data_lake_ods.db/dws_service_subclazz_lesson_user_learn_stat_rt_v2/metadata/00059-1d8e6694-f873-45a3-9697-ce2762f78c3a.metadata.json
4、找到"current-snapshot-id" : 5677214384524195741。其实和建表中的id一样
"current-snapshot-id" : 5677214384524195741,

"schema-id" : 0
}5、得到manifest-list文件路径，下载到本地分析
hadoop fs -get /user/hive/warehouse/data_lake_ods.db/dws_service_subclazz_lesson_user_learn_stat_rt_v2/metadata/snap-5677214384524195741-1-644d4e57-0953-40c0-915d-faf7dd8a3ab2.avro ~/wangshida/iceberg
6、查看avro文件内容
java -jar ./avro-tools-1.8.1.jar tojson ./snap-5677214384524195741-1-644d4e57-0953-40c0-915d-faf7dd8a3ab2.avro | less |grep '5677214384524195741'
内容如下：
{"manifest_path":"/user/hive/warehouse/data_lake_ods.db/dws_service_subclazz_lesson_user_learn_stat_rt_v2/metadata/644d4e57-0953-40c0-915d-faf7dd8a3ab2-m0.avro","manifest_length":12233,"partition_spec_id":0,"content":0,"sequence_number":59,"min_sequence_number":59,"added_snapshot_id":567721438452419574,"added_data_files_count":16,"existing_data_files_count":0,"deleted_data_files_count":0,"added_rows_count":611418,"existing_rows_count":0,"deleted_rows_count":0,"partitions":{"array":[]}}
