The REMOVE statement is used to unload a table from memory.
specifies the table to unload from memory. For a table that was loaded from a SAS library, the table specification is the same libref.member-name that was used to load the table. For a table that was loaded from HDFS, the table specification is the same as the HDFS path to the table, but is delimited with periods (.) instead of slashes (/). For a table that was loaded from the / directory in HDFS, the table specification is HADOOP.TABLENAME.
