hive 數據歸檔問題

1、對數據進行歸檔

alter table tableName archive partition(current='2020-07-02');

報錯如下：
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. org/apache/hadoop/tools/HadoopArchives
查看hive的日志，日志文件在 ls /tmp/${USER}/hive.log
java.lang.NoClassDefFoundError: org/apache/hadoop/tools/HadoopArchives

3、分析
hive在進行歸檔的時候需要使用到hadoop的archive相關的類，但是在hive的lib目錄下面沒有。
2、解決辦法：
從hadoop的lib目錄下拷貝archive相關類到hive的lib下面

① 找到相關類
[hduser@yjt hive]$ find /data1/hadoop/hadoop/ -name *archive*
② 拷貝
cp /data1/hadoop/hadoop/share/hadoop/tools/lib/hadoop-archives-2.9.2.jar /data1/hadoop/hive/lib/

3、開啟archive功能

hive> set hive.archive.enabled=true;

4、測試
歸檔前：

開始歸檔：

hive> alter table hive_text archive partition(folder='docs');
intermediate.archived is hdfs://yjt:9000/user/test/hive_text/folder=docs_INTERMEDIATE_ARCHIVED
intermediate.original is hdfs://yjt:9000/user/test/hive_text/folder=docs_INTERMEDIATE_ORIGINAL
Creating data.har for hdfs://yjt:9000/user/test/hive_text/folder=docs
in hdfs://yjt:9000/user/test/hive_text/folder=docs/.hive-staging_hive_2020-07-07_14-39-31_376_7443789806325398792-1/-ext-10000/partlevel
Please wait... (this may take a while)
Moving hdfs://yjt:9000/user/test/hive_text/folder=docs/.hive-staging_hive_2020-07-07_14-39-31_376_7443789806325398792-1/-ext-10000/partlevel to hdfs://yjt:9000/user/test/hive_text/folder=docs_INTERMEDIATE_ARCHIVED
Moving hdfs://yjt:9000/user/test/hive_text/folder=docs to hdfs://yjt:9000/user/test/hive_text/folder=docs_INTERMEDIATE_ORIGINAL
Moving hdfs://yjt:9000/user/test/hive_text/folder=docs_INTERMEDIATE_ARCHIVED to hdfs://yjt:9000/user/test/hive_text/folder=docs
OK

歸檔后：

5、解壓歸檔文件

hive> alter table hive_text unarchive partition(folder='docs');
