Explain about the smb join in hive?

Answer Posted / Lalit Mohan Gupta

SMB Join in Hive is not directly supported. Hive primarily works with data stored in Hadoop Distributed File System (HDFS), and external data can be joined using a UDF (User Defined Function). To perform an SMB join, you need to mount the SMB share as a Hadoop filesystem and use Hive's JOIN command. However, it's recommended to avoid SMB for large datasets due to performance issues.
