What is the difference between EXPLODE and LATERAL VIEW EXPLODE in Hive?
October 15, 2021Hive architecture
October 22, 2021As simple as this question sounds, we get this question a lot. So we decided to write a post on finding the version of Hadoop and Hive.
Hadoop version
Execute hadoop version to find the version of Hadoop.
[hdfs@wk1 osboxes]$ hadoop version Hadoop 2.7.3.2.6.5.1175-1 Subversion git@github.com:hortonworks/hadoop.git -r 3091053c59a62c82d82c9f778c48bde5ef0a89a1 Compiled by jenkins on 2019-06-20T10:12Z Compiled with protoc 2.5.0 From source with checksum abed71da5bc89062f6f6711179f2058 This command was run using /usr/hdp/2.6.5.1175-1/hadoop/hadoop-common-2.7.3.2.6.5.1175-1.jar
Hive version
Execute hive –version to find the version of Hive
[hdfs@wk1 osboxes]$ hive --version Hive 1.2.1000.2.6.5.1175-1 Subversion git://ctr-e139-1542663976389-113618-01-000015.hwx.site/grid/0/jenkins/workspace/HDP-parallel-centos7/SOURCES/hive -r 97227314513877d194dc15c071fe4e4b8fa3d781 Compiled by jenkins on Thu Jun 20 13:28:19 UTC 2019 From source with checksum f61cb81cd81991486cda043eba9271ca
